Description of the invention ()) [Background of the invention] ^^^^ 1 ^ nf ^ — «m n > — m4 tml · n ^ i I. ^^ i · — 1 tm m ^ i ^ — ^ 1 «-" i (please read the notes on the back before filling in this education) In the past ten years, the Dyeing Oscillator (DMO) has been used as the adjustable orange light source for ultra-high resolution sources. Degree, as an important role in isotope separation experiments. When they began to develop, DMOs represented an unforgettable engineering achievement because they operated at high repetition rates (such as a few kilohertz), with high beam quality and spectral purity. Its output power is sufficient to drive high gain with low A S E and the dye amplifier chain to saturation. Various issues and performance limitations related to DMO and other sub-wavelength locking and spectrum formatting devices (ie, waveform generators or W F G) have been noted over the past few years. D M 0 is constructed by customer-specific mechanisms and optical components. Some optical components have longer transit times (such as stained cells), while others are difficult to properly test before use. For example, an internal cavity calibration instrument has a highly reflective coating on two opposite sides, thus making flatness and fineness testing difficult. Furthermore, the structure and alignment of DM 0, one of the single-mode operations, is a challenging task. Even if a new D M 0 is used, the electronic lock ring and wavelength lock for single-mode operation are typically not very stable, therefore, making the excessively long operation time unrealistic. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and the Industrial Cooperatives Cooperative Association 5! Several WF G system problems occur with the use of DM0. First, because they produce short pulses (ie, tens of nanoseconds), standard Michelson interferometers cannot measure their wavelengths correctly. Second, the synchronization of the D M 0 injection pulses relative to the dye chain pumping pulses must be carefully optimized. Third, pumping pulse time jitter is a problem. Fourth, a maintenance with high chemical purity and ultra-stable (± 5 mK) temperature control requires a reliable 'drift-free DM 0 operation. Fifth, when the dye is pumped, the photochemical treatment of the dyeing solution This paper size applies to Chinese national standards (CNS > A4 size (210X 297 mm) -4- S81 0 A7 B7

5. Description of the invention (2) (Please read the precautions on the back before filling out this page) The chemical degradation will occur, and the concentrated dye solution needs to be added regularly to maintain a specific pumped absorption coefficient. Sixth, the DMO pumping of the impact dye cells eventually caused damage and required repair. There are several kinds of light sources that can be used in the isotope separation system to replace the D M 0 W F G in the isotope separation system. For example, the use of forward spectrum and spatially filtered pulses to amplify the CW-stained laser provides a satisfactory peak-to-peak power level that is substantially free of A S Ε. However, these systems typically require significant dye injection maintenance and often exhibit unstable wavelength locks. A second method using a grazing incidence pulse dye laser provides the advantage of simple design, but this method still has many shortcomings related to short pulse dye lasers. In addition, this method does not meet the spectrum requirements of a typical isotope separation system. A third method uses a solid-state rare earth ion laser. Although some of these lasers can be pumped as laser diodes and / or implemented in a CW mode, they typically have limited adjustability. In the fourth method, a solid-state conversion metal ion laser can be used, and it is preferably operated in a wavelength range of 1.1 to 1.3 microns. These laser systems are mainly based on the T 2 — A 2 transformation of the octahedral cr 3 + and the tetrahedral C r 4 +. In principle, although it can involve customer crystal growth, these laser multipliers can provide the desired processing wavelength. Because the emission conversion generally has a small profile and short life, and because the crystal loss is quite large, the laser threshold is very high. The development of this narrow-line laser with a spatial mode quality suitable for effective frequency doubling seems reasonable, but still needs to be demonstrated. In the fifth method, a single-space mode diode laser in the 1.1-1.3 micron region can be completed for low-temperature operation at a power level of several hundred milliwatts. The frequency doubling of these devices will provide the desired processing wavelength. However, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -5-

A7 B7 V. Description of the invention (3) The structure of the diode laser in this wavelength range is considered to have inherent difficulties. In the sixth method, if the line width is sufficiently narrow, a short pulse and an optical parametric oscillator (0 P 0) can be used. This may require a switch to double the resonant design and reduce the oscillation threshold. However, this may cause difficulties in mode jumps and adjustments. [Inventive Summary] The present invention provides an adjustable visible laser system. This laser system can be used as an alternative to dyed lasers in isotope separation systems. In addition, the laser system can be used as a resonant radiation source for processing monitoring, chemical analysis, laser radar, spectrum analyzer 'fluorometer, projection display and communication. In one aspect of the invention, at least one diode is pumped and coated. The mirror-doped single-mode fiber laser system is mixed with a single erbium-doped: mirror aluminum garnet laser. For each mirror: quartz laser, a pair of Bragg gratings are used to force them to a desired wavelength. The Bragg grating can be adjusted by temperature or pressure. In another aspect of the present invention, the summing mixing is used to mix the output of the erbium-doped mirror aluminous laser with one or more mirrors: the output of the quartz laser. The frequency mixing is performed in a non-linear crystal, such as Li Nb 0 3 or a periodic lithium niobate crystal. In another aspect of the present invention, a feedback loop is used to control the output of the neodymium-doped mirror aluminum garnet laser and mirror: quartz laser. The system uses a CW wavelength meter to measure the output of each laser. The monitored frequency is used to control the output of individual lasers.

(Please read the precautions on the back before filling this page) Laser 1 0 5 is preferably fixed at a wavelength of about 1 3 1 9 nm. — Appropriately hinged aluminum garnet lasers are manufactured by Lightwave's model 1 2 6-1 3 1 9 — 3 50. This laser system is an adjustable single-mode laser ’which has a thermal drift below 50 Μ Η z / hour. Preferably, 'laser 10 1-10 3 series narrow band mirror: quartz laser. Alternatively, the lasers 101-103 may be wide-band mirrors: quartz lasers, for example, one having a bandwidth of about 4 nanometers, which is resonant to complete the desired frequency bandwidth. Preferably, this is done with an F B G to provide adjustability by changing the period of the thermal grating. Fiber gratings are already available in several standard wavelengths from the New Focal Model 5900 series. Installing a fiber grating with a proper period will guarantee operation close to the wavelength you want to process ‘so’ only fine tuning is required. For example, ultra-narrow bandwidth lasers with sub-M Η ζ linewidth lasers have been manufactured.

Regarding the non-linear optical element 107, the main body Li Nb 0 3 is often available and p P LN is more known. Although 'does not exhibit long-term reliability, P P L N is used in the preferred embodiment of the present invention because of its high non-linear coefficient, non-critical matching, and high frequency bandwidth. No matter whether it is Li Nb 03 or 卩 P LN element, it is operated at high temperature to complete the non-adjacent phase matching, which reduces the tendency of optical refraction distortion to laser wave. It is used to generate the sum frequency with non-critical phase matching The theoretical conversion efficiency has been known by the well-known formulas quoted by Musla et al.

dSLP, P where P is the power of each wave, n3 is the critical refractive index of the output wavelength, L is the critical length, de f f is the non-linear optical coefficient, and Zh is the free-space impedance (ie, 37 ohms).

Assume that for L and de f of the main body L i N b 0 3 at 50 mm and 3.3 pm / V, respectively, P 3 is about. Q 1 6 P i P 2. For a neodymium-doped mirror aluminum garnet laser millimeter P P L N with a non-linear 18 p m / V, the P .3 series is approximately 0 ._ 19 P i P 2. Therefore, the conversion efficiency ranges from about 1.0 percent per watt to about 19 percent cents per watt.

In addition, because the FWHM temperature adjustment bandwidth is expected to be several + ° C, and because self-absorption is not serious, stable operation can be achieved without hysteresis. The spectral purity of cw fiber lasers is impressive, especially when the pump power is stable. Line widths below 1 M Η z have been completed, and 値 at k Η ζ have been reported.

Ninth, this system requires less maintenance than the standard D M 0. The use of a true CW main oscillator based on ultra-narrow band lasers, as disclosed today, allows some components of W F G to be simplified. Furthermore, assuming that the visible light signal is of low power and near-refraction, the effective optical fiber transmission system is possible and allows for cost, spacer and alignment time savings at potential. The possible changes in various W F G elements are further illustrated in FIG. 3. The output of ammonium-doped mirror aluminum garnet laser 3 0 1 and mirror: quartz laser 3 0 3 are mixed in SFG of a non-linear crystal (such as Li N B 0 3 or PPL Ν), part of which is Reflected by beam splitter 307. Because the S F G wavelength depends on the two IR input wavelengths, there are two wavelengths to monitor and control. The two can be transported with a single fiber 3 0 9 and separated with a standard communication type wavelength division multiplexer 3 1 1 before being connected to the fiber switch 3 1 3. Appropriate fiber opening relationships are made by J D S Fitel (e.g. * S B series) and by D i C ο η (e.g. MC 5 2 3 series). The output of the fiber switch 3 1 3 is connected to a wavelength meter 3 1 5. A suitable wavelength meter is Burleigh WA-15 00, which provides a frequency measurement with an accuracy of 300 MHz and a display resolution of 10 MHz. Because this wavelength meter includes a computer interface to receive a user set point and send an analog feedback error signal, it can be easily integrated with electronic g sharpening mirror sharp stone talc laser and is.

Description of the invention (彳 彳) is designed to meet peak power, The pulsed laser beam operates with a millimeter-sized aperture, and an RF amplifier 32.3 is required to apply a large RF drive voltage to obtain a sufficient modulation index. In order to prevent the modulators 3 1 9 and 3 2 1 and the resonant circuit from being heated, the preferred RF driver is not applied continuously, but is applied in synchronization with the light waves for pulse application. Low-power light operation with a small beam diameter will likely allow the use of L i Nb 03-based fiber optic flexible lead integrated optical modulators. Representative modulators are made by Single-Phase Telecom Products (formerly United Technologies Photonics) and E-TEK Dynamics. If desired, other bandwidths can be obtained by placing two modulators in series. In a preferred embodiment, one of the dye chains needs to be co-amplified. In other words, the two processing wavelengths are simultaneously amplified in the same medium. In order to achieve the best power separation between the two wavelengths, a power balancing effect is required. Although this effect can be provided by a combination of a polarizer and a high voltage Pockels unit, a low voltage fiber optic flexible lead amplifier modulator is preferably used. Preferably, the modulator 3 2 1 also provides a blocking function: one of the processing wavelengths is interrupted in order to diagnose the photocurrent amplitude. Furthermore, the power separation system for continuous low frequency modulation can be used with locked photocurrent detection to ensure the maximum dynamics of separation work, regardless of changes in steam density, overall laser power, etc. FIG. 4 is a schematic diagram of another embodiment of the present invention.
