RealStable® PA Series Conduction Cooled Polygonal Diode Laser Array
RealStable® PA Series Conduction Cooled Polygonal Diode Laser Array

The PA 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 PA01 is composed of six hexagonally arranged stacks, with three bars in each stack, and each bar has a power of 100W/200W.Other wavelengths and packaging forms can be customized.

1.Please contact sales representatives for customization for other specifications and packaging forms.
2. Do not operate it beyond normal operating conditions, otherwise, the service life of the device might be shortened.
3. A non-condensing and Class 10,000 clean environment is required for storage and operation.
4.The above parameters are measured under QCW mode with pulse width of 250μs and repetition rate of 20Hz at 25℃.
5. As products are constantly being updated, the right of final interpretation of technical specifications or illustrations in datasheet belongs to RealLight.
