807nm, 1800W Laser Diode

The Vertical Diode Laser Stacks from JENOPTIK are QCW (quasi-continuous wave), actively cooled, and collimated laser devices. They are available in five different designs with 4, 6, 8, 10, and 12 submounts. The designs are identified by the product code JOLD-x-QAFN-xA. The laser stacks have high optical output power up to 90 W cw (continuous wave) per bar after collimation, with wavelengths of 808 and 938 nm. They also have high efficiency and low divergences, with a lifetime of over 1 GShot and high reliability.

The laser stacks are ideal for pumping solid-state and fiber lasers, material processing, and medical applications such as hair removal. The specifications of the laser stacks include maximum pulse length/duty cycle, maximum optical output power, operation mode, water flow rate tolerance, water temperature, maximum inlet pressure, and pressure drop. The laser stacks require deionized water with a flow rate of 7-4.3 l/min and a water quality of 2-6 μS/cm. Additional designs or specifications are available upon request.
