Abstract
IN PHASE I OF THIS PROPOSAL WE WISH TO INVESTIGATE A NEW MATERIAL B-BBO AS HIGH AVERAGE POWER AND HIGH PEAK POWER ELECTRO-OPTIC INTRACAVITY POCKELS CELL. SUCH A DEVICE IS REQUIRED FOR DIODE-PUMPED Nd:YAG SOLID-STATE LASERS FOR HANDLING CIRCULATING POWERS UPTO 100 WATTS. PRESENT MATERIALS ARE LIMITED WITH SERIOUS THERMAL HEATING AND SUBSEQUENT DAMAGE DUE TO LINEAR OPTICAL ABSORPTION PROBLEMS. CRYSTAL B-BBO IS AN ORDER OF MAGNITUDE MORE RESISTANT TO THERMAL FRACTURE THAN KD*P OR LiNbO(3). WE PROPOSE TO CHARACTERIZE AND TEST A B-BBO Q-SWITCH FOR HIGH AVERAGE POWER APPLICATIONS AT 1064 nm WITH A Nd:YAG LASER. A B-BBO POCKELS CELL WILL BE FABRICATED WITH A 3x3x10 mm3 ROD AT QUANTUM TECHNOLOGY INC. AND USED IN OUR EXPERIMENTS. B-BBO Q-SWITCHES COULD VERY WELL REPLACE KD*P AND LiNbO(3) POCKELS CELLS FOR SPECIAL APPLICATIONS INVOLVING HIGH AVERAGE POWERS (100W) AND HIGH PEAK POWERS (5GW/cm2).
