Paper Abstract

Using a LD as the pumping source in the CW mode and pulsed mode, we have got the self Q-switched laser in the co-doped Cr4+:Nd3+:YAG laser microchip with 2 mm thickness. When the LD operated in cw mode, the output laser is self Q-switched due to the saturable absorption of the Cr4+ center. Using the cw pumping laser of 3.3 W, the output laser of 3.86 mW operated in the quasi-CW mode with the repetition rate of 13 KHz and the pulse width of 40 ns was obtained. Using the pulsed pumping with 100 Hz repetition rate and 5 ms pulse width, the laser pulse series with several sub-pulses is obtained.
