Kilowatt-class, High Duty Cycle, Passively Side-cooled 780 nm Diode Laser Stacks as Pumps for Pulsed MIR Lasers

Not Accessible

Your library or personal account may give you access

Abstract

A 780nm diode laser pump source is presented that uses passive side-cooling to enable Kilowatt-class output at >10% duty cycle (10ms, 10Hz). Beam quality is M2<360 (BPP<90mm-mrad) and initial reliability test extrapolates over GShot-class lifetime.
