Study on miniature Cr4+:YAG Q-switched repetitive operation conductive cooling (Ce,Nd):YAG laser (II) -: ----Experiments

Upon the theoretical guiding and some related experimental as well as theoretical results concerning the project, a miniature Cr4+:YAG Q-switched, repetitive operation, conductive cooling(Ce;Nd):YAG laser was developed up to practical application level, the laser rod was fixed at a pedestal with a contact angle of about 120 degrees, compacted with an intersecting circles pump cavity, together with a plane-parallel resonator. The main specifications of this laser are listed below. Laser output energy:single pulse:5 similar to 30mJ Repetitive rate:2 similar to 5pps Pulse-width: less than or equal to 15ns Beam divergence:3 similar to 5mrad Limitation of ambient temperature :-40 degreesC similar to 60 degreesC Dimensions:130x30x30.
