ABSTRACT
Laser action at 1.06 μm from a neodymium aluminium borate microchip laser crystal has been demonstrated under 4F3/2 direct excitation at 882 nm. We have found that the laser slope efficiency increases from 50% up to 70% when resonant pumping is used instead of the traditional 4I9/2→4F5/2( 808 nm) pumping. We conclude that the reduction in the pump-induced heat generation achieved by resonant pumping is at the origin of this improvement.
