cw output power levels of 76 and 55 W have been obtained from 1 cm monolithic AlGaAs laser diode arrays with an aperture width of 3 and 2 mm at a heatsink temperature of 0 and 23 °C, respectively. One of the diodes has been operated for over 5000 h at varying power levels between 5 and 10 W and at varying temperatures between 20 and 40 °C and operated successfully for over 3000 h at power levels over 7 W.

    We report on the first diode-laser (nominal 200-mW 10-stripe laser diode) end-pump lasing of Nd:YVO4. The lowest threshold (30 mW) and highest output power (120 mW) were observed from the Nd:YVO4 laser as compared to a similar Nd:YAG laser. Over 50% optical slope efficiency was obtained, the...
