2016 Edition, June 1, 2016 - Optical Society (The) (OSA)

A handheld, battery-powered intracavity singly resonant optical parametric oscillator (IC-SRO) emitting 3.5 μm, 39 mW CW radiation is demonstrated. The lasing threshold of the IC-SRO (end-pumped by a 808 nm diode) is 120 mW.

5 kW Near-Diffraction-Limited and 8 kW High-Brightness Monolithic Continuous Wave Fiber Lasers Directly Pumped by Laser Diodes
2017 Edition, Volume 9, October 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Tandem pumping technique are traditionally adopted to develop >3-kW continuous-wave (cw) Yb3+-doped fiber lasers, which are usually pumped by other fiber lasers at shorter wavelengths (1018 nm e.g.,). Fiber lasers directly pumped by laser diodes have...
