The number of cavity mold number of excitations, while calculating the fineness of resonant cavity, and by the fineness and resonance of the resonant cavity being calculated
The theoretical fineness of chamber compares, until the difference of the two is in certain threshold range.
The working principle of the invention：
The correct adjusting of resonant cavity includes following meanings：Incident laser only excites the basic mode of resonant cavity, any without exciting
One high-order mode, in other words, the beam waist position and size of incident laser and the beam waist position and size of resonant cavity want completely the same
（I.e. the beam waist position coincidence of the two, radius are equal）.Therefore, the adjustment process of resonant cavity is actually to select of certain focal length
It with lens, and determines the position of matching lens in the optical path, coordinates the position between light source, matching lens resonant cavity hysteroscope three
Set the process of relationship.In the adjusting of resonant cavity, to meet above-mentioned requirements, need to do the following：Firstly, incident laser
Optical axis wants coaxial with resonant cavity axis；Secondly, the position and size with a tight waist of the resonant cavity with a tight waist of incident laser wants completely the same.
Otherwise, it inevitably will appear the excitation to resonant cavity high-order mode in experimental implementation, reduce the signal-to-noise ratio of monitoring.
Most of incident laser due to mid-infrared laser light source output can not be observed directly with eyes, optical path
Adjusting is carried out firstly the need of by visible light, and regulating step can substantially be divided into coarse adjustment and fine-tuning process, due to real process
Encountered in the case where be unable to prophet, therefore, it is also desirable to according to the actual situation in due course adjustment.
Coarse tuning process：In adjustment process, light source using He-Ne visible laser 2 as collimated light path, collimated light path
As shown in Figure 2.When carrying out beam path alignment, two pieces of hysteroscopes of resonant cavity 5 are substituted with two adjustable diaphragms 63,64, pass through tune
The position for saving He-Ne visible laser 2, semi-transparent semi-reflecting lens 3 and two pieces of total reflective mirrors 41,42, makes He-Ne visible light while passing through
The aperture of four adjustable diaphragms 61,62,63,64.After beam path alignment, coarse adjustment first is carried out to resonant cavity 5 with He-Ne visible light：It will
Two pieces of hysteroscopes 51,52 of resonant cavity 5 are reattached to the both ends of resonant cavity 5, and other each section positions remain unchanged, such as Fig. 3 institute
Show.The opposite depth of parallelism between two pieces of hysteroscopes 51,52 is adjusted, He-Ne visible light-transmissive resonant cavity 5 on receiving screen 8 is observed and warp is poly-
Generated interference ring after focus lens 7 are assembled, until the He-Ne visible light through resonant cavity 5 generates apparent interference ring,
At this moment if giving piezoelectric ceramics（Piezoelectric ceramics be close to resonant cavity incidence end hysteroscope 51 on the outside of be arranged and with 51 ruler of incidence end hysteroscope
It is very little identical）Apply the control voltage of a cycle variation, so that it may observe the vibration frequency and scanning piezoelectricity pottery of interference ring
The frequency of the control voltage of porcelain is consistent, arrives this, it is believed that works the coarse adjustment of resonant cavity 5 and completes.
Fine-tuning process：Since He-Ne visible light can directly be observed with eyes, to the coarse adjustment work phase of resonant cavity 5
To more intuitive.The result of fine tuning can only be judged by the transmission peaks being shown on oscillograph 10, due to the transmission of resonant cavity 5
Peak intensity is weaker, needs the data of oscillograph 10 being averaged by more number, therefore response is lagged, to next thin
Work is adjusted to increase very big difficulty.Fine-tuning process is as follows：
（1）He-Ne visible laser 2 is closed, opens tunable middle infrared semiconductor laser 1, it is red in fine adjustments
The incident direction of outer laser and position, the direction of infrared photographic plate observation mid-infrared laser, makes light beam while passing through optical path in
In two adjustable diaphragms 61,62 aperture, observation mid-infrared laser through resonant cavity 5 and line focus lens 7 assemble, detector
The transmission peak-to-peak signal of the resonant cavity 5 shown on oscillograph 10 after 9 detections, as shown in Figure 4.
（2）After the transmission peak-to-peak signal for observing resonant cavity 5 on oscillograph 10, continue to fine-tune entering for mid-infrared laser
Penetrate direction and position, it can be seen that the transmission peaks of resonant cavity 5 become have regularity, and mode configuration gradually shows, because incident
Laser regularly excites a few cavity mold since original dispersion excitation multimode, and the energy of exciting light gradually focuses on minority
In several cavity molds being excited, therefore, the intensity of the transmission peaks of resonant cavity 5 is gradually reinforced.
（3）If the position for continuing to adjust incident laser cannot be such that the intensity of transmission peaks continues growing, should will just match
Lens 11 are added in optical path, carefully adjust the position of matching lens 11, make preferably to meet mould between incident laser and resonant cavity 5
Formula matching relationship makes the energy quantity set of the overwhelming majority so that incident laser be made further to be suppressed the excitation of resonant cavity high-order mode
In in individual several cavity molds.At this moment, the transmission peaks of resonant cavity 5 are not only more regular, and intensity is stronger.
（4）It is adjusted if necessary to further, then it must be by the position of tunable middle infrared semiconductor laser 1, matching
The position of lens 11 and two pieces of joints of hysteroscope 51,52 are adjusted, and the final single-mode launching for realizing incident laser to resonant cavity 5 makes humorous
The transmission peak intensity of vibration chamber 5 reaches maximum.This adjustment process will not only observe variation and the incident laser pair of transmission peak intensity
Cavity mold number of excitations number, it is often more important that constantly with relational expression F=FSR/FWHM calculate resonant cavity 5 fineness,
In, FSR indicates free spectral range, and FWHM indicates peak half breadtgh, and compared with the theoretical fineness of resonant cavity 5, until the two
Until being worth relatively.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made, should fall within the scope of protection determined by the claims of the present invention.
