| Abstract: | The characteristics of Cr4+, Nd3+:YAG are presented. A self-Q-switched Cr4+, Nd3+:YAG laser pumped by fiber-coupled diode laser produces 1064 nm pulse laser with the average power of 3.36 W, the pulse duration of 65 ns, and the repetition rate of 87 kHz. The opto-optical efficiency is 15.3%. When the KTP crystal is inserted into the cavity, the 532 nm green pulse laser is obtained. The average output power is 1 W, the pulse duration is 210 ns, the repetition rate is 47 kHz, and opto-optical efficiency is 6%. |
