Nd: BGO is a promising laser crystal as well as a useful magneto-optic medium. A diode laser pumped Nd: BGO laser at 1. 04 μm has been succeeded for the first time. CW output power of 40 mW with TEM00 mode and efficiency of 13. 3% have been obtained. The pumping threshold is 25 mW. Using the faraday rotational effect, we calculated the parameters of the diode laser pumped self Q-switched Nd:BGO laser. In which the magneto-optic modulator consists of the Nd:BGO crystal itself and a Brewster glass plate. Pulsed energy of 2 μJ with width of 100 ns has been detected at a repetition rate of 1 kHz.
