938nm, 1080W Diode Laser Stack

The Vertical Diode Laser Stacks from JENOPTIK are qcw (quasi-continuous wave), actively cooled, and collimated laser modules that come in five different designs with 4, 6, 8, 10, and 12 submounts. They have high optical output power up to 90 W cw (continuous wave) per bar after collimation, with wavelengths of 808 and 938 nm. The laser stacks have high efficiency, low divergences, and a lifetime of over 1 GShot, ensuring high reliability.

They are suitable for various applications such as pumping solid-state and fiber lasers, material processing, and medical applications like hair removal. The specifications of the JOLD-x-QAFN-xA designs include maximum pulse length/duty cycle, maximum optical output power, and operation mode. The laser stacks require water cooling with specific flow rate tolerance, water temperature, maximum inlet pressure, and water quality.
