Abstract
The present invention provides a temperature regulation method for frequency doubling crystals inside optical resonators, belonging to the laser technical field. The regulation method of adopting a temperature regulation device for frequency doubling crystals inside optical resonators is that: power is turned on to detect whether a refrigeration unit and a circulation waterway are in normal operation or not, and a temperature control switch is set at 24 DEG C, then the relative light path position and orientation of a crystal arranged on a 3D regulation frame are accurately adjusted and positioned. When an optical resonator is in normal operation, the laser light passing through a frequency doubling crystal increases the temperature of the crystal, and when a sensor senses that the frequency doubling crystal as well as the water temperature exceed 24 DEG C, the temperature control switch is turned on for refrigeration; when the water temperature is lower than 24 DEG C, the temperature control switch is turned off, and the refrigeration unit stops operating, thus the temperature regulation is realized. The present invention can truly measure the non-optical plane temperature of the frequency doubling crystal in the actual working state, which is convenient for regulation and control, thereby improving the laser conversion efficiency and life span of the frequency doubling crystal. The method is accurate, practical, low in cost and convenient for popularization.

Background technology
Temperature should be controlled at about 24 ℃ in use at the scene of doubling frequency crystal in optical resonant cavity, surpasses this value the frequency-doubling crystal internal temperature is raise, and causes conversion efficiency to reduce, have a strong impact on power output.The type of cooling of frequency-doubling crystal all adopted the method for indirect water-cooling in the past, was about to frequency-doubling crystal and packed into to conduct heat to tighten up in the good red copper material and use or the red copper material is being added the water jacket cooling.These method effects are very undesirable in the real work, the very big damage that also can cause frequency-doubling crystal sometimes of thermometric indicating value and true value error.
Summary of the invention
In order to solve the problem that exists in the background technology, overcome and surveyed shortcomings such as frequency-doubling crystal surface temperature error is big, regulation and control poor accuracy in the past when optical resonator was interior works.The present invention adopts the non-optical plane of frequency-doubling crystal directly to invade the method for carrying out temperature adjusting in the recirculated water.Promptly the thermometric contact by temperature sensor directly with the non-optical plane contact thermometric of the frequency-doubling crystal error of indication ± 1 ℃. be connected on the water temperature variation around the non-optical plane of water temperature regulate and control frequency-doubling crystal in the evaporator of water route refrigerating system by temperature detect switch (TDS) control.
The device that technical solution of the present invention adopts comprises: compressor, condenser, hydrone filter, capillary, temperature detect switch (TDS), transducer, indicating value table, evaporator, crystal bracing frame, crystal coolant jacket, water nozzle, water pipe, the solid glue of water, crystal, three-dimensional adjustable shelf, magnetic drive pump, copper tube.
Its static annexation is: at first with the compressor in the refrigerating units, condenser, hydrone filter, capillary, temperature detect switch (TDS), transducer, indicating value table, evaporator serial connection, transition connects uses copper tube.The evaporator outlet pipe is connected with the magnetic drive pump water inlet; The magnetic drive pump delivery port is connected on the water inlet tap on the crystal coolant jacket, the faucet of crystal coolant jacket is connected on the evaporator water inlet tap and forms circulation waterway.Frequency-doubling crystal with in special fixture, assemble being connected of crystal bracing frame and the solid glue sealing and fixing of water, and attach it on the crystal coolant jacket and the solid glue sealing and fixing of water after together be installed on the three-dimensional adjustable shelf.
Temperature adjusting method is as follows:
At first whether the work of energising inspection refrigerating units is normal, whether circulation waterway is normal, and temp control switch is set 24 ℃,
The crystal relative light path position and the orientation adjustment that are installed on the three-dimensional adjustable shelf are accurately also located.
Laser by frequency-doubling crystal when the optical resonator operate as normal raises its temperature, will measure temperature value by transducer and be presented on the indicating value table; When transducer 6 measure frequency-doubling crystal and water temperature thereof when surpassing 24 ℃ temperature detect switch (TDS) connect refrigerating units and make its work refrigeration reduce the temperature of recirculated water; Temperature detect switch (TDS) disconnects when transducer measures frequency-doubling crystal and water temperature thereof less than 24 ℃, and refrigerating units quits work.So just realize the temperature adjusting of doubling frequency crystal in optical resonant cavity.
The present invention can serious actual measured amount be convenient to reconcile control to the non-optical plane temperature of frequency-doubling crystal actual working state, thereby has improved the laser-conversion efficiency of frequency-doubling crystal and the useful life of frequency-doubling crystal.This method is accurately practical, and cost is lower, is convenient to promote.
