Heat capacity type neodymium glass flaky laser

Abstract

The invention discloses a neophane glass piece laser in heat capacity type. The invention is characterized in that the invention comprises a resonant cavity and an octagonal silvering reflector. The resonant cavity is a virtual confocal cavity which comprises a total reflective mirror and an output mirror; the octagonal silvering reflector is internally provided with a plurality of laser glass pieces which form 45 DEG with an optical axis; the optical axis of the laser glass piece is coincident with the optical axis of the resonant cavity; the upper side and the lower side of the laser glass pieces are respectively provided with pumping lights which are arranged in the reflector; the discharging direction of the pumping light is parallel to the direction of the laser; the pumping light is coaxially and hermetically sleeved with a cerium-doped quartz pipe; cooling water is arranged between the quartz pipe and the pumping light; the invention has the advantages of simple structure, obtaining the laser output with high energy and high power by operation under high repeated frequencies in short time, uniform and stable laser output, recovering the glass working medium to original state in the operation interval of the device and avoiding the thermal lens effect and the thermal stress effect to the laser device.

Description

technical field [0001] The invention relates to a laser, in particular to a heat capacity neodymium glass sheet laser. Background technique [0002] Due to the extremely poor thermal conductivity of laser glass, when operating at a high repetition rate, the severe thermal lens effect will shatter the laser, and the thermal stress will cause the laser glass to break. In order to overcome this shortcoming, many different lasers have been developed, such as thermal The capacitive moving plate glass laser is characterized by the movement of the laser medium, so that the flash lamp pumps a local area of ​​the glass to generate laser light at a certain moment, and pumps another area at another moment. The local pumping can achieve a higher power density. In order to obtain high laser efficiency, and the cooling is distributed on the entire plate surface, high average power laser output can be achieved, but the output power of the entire laser device is limited by the load capacity...
