Abstract
Summary form only given. A 2D microchannel cooled, monolithic surface emitting array operating at 808 nm, has been used to pump a 400 μm thick wafer of Nd:YVO4. The 12 by 8 diode array is collimated with fiber lenses to pump 80 μm diameter spots. The array area has a cross-section of approximately 0.5 cm2. Thermal lensing, produced by pump light absorption, provides cavity stability for each microlaser cell in the array. The Nd:YVO4 wafer was AR coated on the pumped side at 808 nm and HR coated at 1.064 μm
