Diode-pumped micro-laser arrays. Final report, 30 September 1993-18 February 1994
In this work, SDL investigated the operation of 2-D high power micro-laser arrays based on novel monolithic surface-emitting laser diode arrays coupled to Yb:YAG and Er:YSGG micro-laser crystals. The experimental demonstrations include: (1) 200 mW, q-cw single Yb:YAG microlaser; (2) 930 mW cw linear, 12-element Er:YSGG micro-laser; (3) 130 Watt q-cw 2-D surface-emitting laser diode array at 970 nm; and (4) 600 mW, q-cw from an 18-element 3-D Er:YSGG microlaser array. The experiments performed at SDL under this contract demonstrate the suitability of monolithic 2-D laser diode arrays for pumping solids state lasers. In addition, the experiments show the flexibility of the micro-laser concept. Using different pump wavelengths in combination with different micro-lasers a wide output wavelength range from 1 micron to 3 micron is demonstrated. Finally, the micro-laser array is shown to be scalable by exploiting one- and two-dimensional laser diode pump arrays.
