Abstract
All-solid-state compact blue and green lasers are required for low-power applications in the medical and reprographics industries. Our group recently reported 13 mW of green1,2 and 1 mW of blue3 radiation generated from diode-pumped composite-material microchip devices. In addition Zarrabi et al. generated 15 mW of blue radiation from a Ti:sapphire laser-pumped Nd:YALO/KNbO3 microchip.4 We report here on a diode-array-pumped Nd:YAG/KNbO3 blue microchip laser generating over 25 mW and 5 mW of 473-nm radiation using a 1.2 W and 0.5 W diode array respectively.
