The Derringer package features a proprietary water cooling design that enables excellent heat extraction without the need for deionized water. The arrays are well-suited to side-pumping of solid-state laser (SSL) crystals, as well as any direct diode application which requires multiple bars in a linear configuration. The 3-long Derringer features an emission output length of approximately 3 cm. CW output powers of up to 120W are available. For QCW configurations, the maximum output is 7.2 kW out of a 24-bar array.
