Laser Diode by Northrop Grumman

Note: Your Quotation Request will be directed to Northrop Grumman.

The ARR291P1800 from Northrop Grumman is a Laser Diode Array of 8/10/12 laser diode bar stacks that operates at a wavelength of 790 to 1550 nm. It delivers a QCW output power of 1800 W (150 W per bar) with a slope efficiency of 15 W/A and electro-optical efficiency of 55%. This laser array has a beam divergence of up to 38x7° and a pulse duration of 0.5-300 ms. It is assembled with hard AuSn solder and expansion matched materials for increased reliability and is cooled by Non-Deionized standard filtered water, making installation and maintenance more cost and time efficient. This laser has fast-axis and slow-axis collimation lensing options available. It requires a DC supply of 24 V and consumes 140 A of current. This laser array is available in an H package and is ideal for material processing, LiDAR, laser peening, Ti:S pumping, laser cutting and direct diode applications like hair removal and plastic welding.
