Abstract
A multimode source, such as a high-power laser diode bar, to pump an Nd doped region defined in a cavity of a monolithic crystal structure. The axial length L of the doped region is chosen to optimize energy absorption from the multimode source while minimizing resonant re-absorption loss to unpumped Nd ions. The next proximal cavity length L is an undoped region whose length is chosen to optimize the lowest order or fundamental spatial mode (“mode ”) of the cavity. Advantageously, multi-parameter numerical optimization techniques may be employed in which the parameter set (e.g., doped length, L , doping concentration, pump beam spot size, micro laser cavity length, and output coupler reflectivity) is varied to determine the overall optimal length L .
