Laser Diodes

Microchannel Cooled Stacks

The Microchannel Cooled Stack (MCS) features state of the art cooling that enables superior heat extraction, thereby allowing for higher output powers than are available with other laser diode array styles. The MCS is available with continuous wave (CW) or pulsed (QCW) laser diode bars and can be stacked with up to 60 bars. The CW configuration is rated at up to 100 W per bar depending upon the wavelength, with standard wavelengths offered in the range from 780 nm – 980 nm and custom wavelength options available upon request. MCS arrays can be micro-lensed with a typical fast-axis collimation of ≤ 0.25° (FWHM) and are ideal for high brightness applications.


  • Ideal For High Brightness Applications
  • DI Water Cooled
  • High Average and Peak Powers
  • Multi-Wavelength Configurations
  • Up to 100 W CW Per Bar
  • Fast & Slow Axis Collimation Available
