Requirements of pump diodes for diode-pumped solid state lasers

摘要

Abstract: We report on the influence of the different specifications of a single emitter laser diode (type A) and a laser diode (LD) of the partially phase locked type (type B), on some characteristics of our diode pumped solid state lasers (DPSSL). We find that the use of the type B LD is preferable to that of type A with respect to smaller M$+2$/ of the DPSSL-beam, superior noise behavior, and smaller full width at half maximum of the LD emission.!0
