WA-4 Series Water Cooled Diode Laser Array

WA-4 Series water cooled diode laser array is a high peak power diode laser array product developed by RealLight. The WA-4 series is composed of 4 stacks arranged in a linear configuration, with 1-3 bars in each stack, and each bar has a power of 100-250W. This diode laser array delivers quasi-continuous wave output. Other wavelengths and packaging forms can be customized.
