Description
Technical field
The invention belongs to field of photoelectric technology, specifically provide a kind of adjustable crystal thermostat of mechanical location.
Background technique
With the continuous development of laser technology, laser is widely applied to the necks such as military, medical treatment, industry and scientific research
Domain, along with the extensive use of laser, laser the relevant technologies are also continued to develop.In the laser, laser match two frequencys multiplication,
Frequency tripling technology has been used fairly common, and the maximum feature of this method is that structure is simple, easy to adjust.But except unthreaded hole effect it
Outside, the disadvantage of this technology is that crystal match angle varies with temperature so that two frequencys multiplication, frequency tripling beam energy are unstable, especially
It is in the laser of high-power output, secondly frequency multiplication, frequency tripling output beam energy are very big with the variation of crystal temperature effect.It seeks
It asks a kind of temperature-controlled precision to be suitble to requirement, is to realize that angle matching is stablized two frequencys multiplication, frequency tripling crystal constant temperature more than room temperature
The key of output.
In existing technology, mainly it is fixed crystal thermostatic chamber.Such as cylindrical thermostatic chamber, outside flat-temperature zone
Side is heat source body, inner wall blacking, and heat source body fills thermal insulation material, keep all directions heat insulation effect consistent around heating furnace silk, outside.It is permanent
Warm area longitudinal direction both ends set seal glass, and frequency-doubling crystal device can be dismounted by removing seal glass.Using p-n junction temperature sensor come
Carry out thermometric.But the crystal constant temperature chamber device is complicated, assembling difficulty is big, and cannot change mechanical angle or position, because
This is not easy to tuning wavelength, and application range is small.
Other than crystal angle to be adjusted carries out the conventional crystal of wavelength tuning, had been developed later new periodic polarized
Crystal, such as PPLN.For PPLN due to nonlinear factor height, damage threshold is big, and wavelength easily tunes, and is just widely applied quickly.But
Due to there are photorefractive effect, when use, needs to increase its temperature.Its wavelength tuning mode is also different, can pass through mechanical location
Adjustment carry out wavelength tuning, can also pass through thermal tuning.Used at present is all traditional crystal thermostat, unfavorable
In tuning wavelength, limit its application.
Compared with the optical parametric oscillator that pulsed light mode is run, the oscillation threshold of continuous wave optical parametric oscillator is higher,
Transfer efficiency is low, develops slowly always.The appearance of the PPLN crystal of high efficiency Low threshold is greatly promoted infrared in high power
The development of continuous laser technology.It is limited by preparation process, large-size crystals are not easy to obtain, while crystal length is longer to optical path
Adjustment precision requirement is higher, and high power laser is selected to become main means as pumping source, swashs especially with large-power optical fiber
Light device；Increase the power density of pumping light using the method that lens or lens combination focus, it is also possible to obtain stronger parameteric light
Output, but if the facula area focused is too small, will increase the angle of divergence of light beam, exceed the permitted model of phase matching angle
It encloses, transfer efficiency is caused to reduce, the too strong plated film for being easy to damage crystal itself and hysteroscope of this exterior focusing.It is therefore desirable in conjunction with
It is copolymerized burnt condition value to calculate, selects suitable chamber long and the focal length of lens, so that the best pattern match of pumping light and chamber, to obtain
Obtain optimal high-power output.
