RealStable® PA-2 Series Conduction Cooled Polygonal Diode Laser Array
The PA-2 series of conductive cooled polygonal diode laser array is a high peak power product developed by RealLight for use at high temperatures of 60°C. The PA-2 series is composed of twelve hexagonally arranged stacks, with 1 ~ 4 bars in each stack, and each bar has a power of 100W/200W. Other wavelengths and packaging forms can be customized.
