| Abstract(in English) | We are developing diode end-pumped high-brightness Cr^<4+>:YAG passively Q-switched Nd3+:YAG microchip lasers. In order to improve the peak power of the laser, we have measured the dependence of the initial transmission of saturable absorber and the cavity length. The mechanism of the passively Q-switching in the Nd^<3+>:YAG laser with Cr^<4+>:YAG crystals as a saturable absorber has been analyzed. A rate equation model that accounts for the final transmission of the saturable absorber was developed, and good agreement between the modeling and experiments was observed.As a result, its maximum output pulse energy 0.58mJ with the pulse width of 870ps and the peak power was 670kW with 1 OOHz repetition frequency and a beam quality of M^2 = 1.11. |
