808nm, 40W Laser Diode

The LumiLase and RangerLase mounted high-power laser bars cover the near-infrared wavelengths range 808…1550nm. The bars are mounted on robust, industry standard CS-type heat sink. The LumiLase bars provide very high conversion efficiency and high brightness. The Rangerlase products are targeted for applications where eye-safe wavelengths are preferred. These multimode laser bars provide efficient and stable laser light output in CW operation.
