A review of diode-pumped lasers

Advances in Lasers and Applications, 2021
Decreasing costs of diode lasers and increasing diode powers have gone hand-in-hand and so fuelled this interest in diode-pumped lasers. As these trends continue, so there is an inexorable move towards diode-pumped lasers of ever greater power. The earlier prevailing notion that diode-pumped lasers are free from pump-induced thermal effects, has long ...

Efficient laser diode pumped Nd lasers

Applied Optics, 1989
Results are presented for laser diode axially pumped Nd:YAG and Nd:BEL lasers. For Nd:YAG, in excess of 870 mW was obtained with a differential slope efficiency of 56%, and for Nd:BEL in excess of 635 mW was obtained with a slope efficiency of 46%. Electrical efficiencies of 13.0 and 9.5% were recorded for Nd:YAG and Nd:BEL, respectively.

Diode pumped alkali lasers

SPIE Proceedings, 2011
Diode pumped alkali lasers attract growing attention during the past several years because they have demonstrated potential to compete and, possibly, replace the best existing high power laser systems. In spite of the fact that an optically pumped alkali (potassium) vapor laser was first proposed by A.L. Schawlow and C.H.
