All-solid-state diode-pumped eyesafe lasers

An eyesafe source at 1.61 J.UD with 2.1 % wallplug efficiency, is demonstrated using a Nd:YAG pumped KTP optical parametric oscillator with total peak-power conversion efficiency of 70% and an energy conversion efficiency of 47 % to 1.61 J.UD or 30% to l.54J.UD.
