808nm, 100W QCW Laser Diode

The JOLD-70-QPXF-1L from JENOPTIK fiber-coupled diode lasers are passively cooled and designed for qcw operation mode. They have a maximum pulse length of ≤ 0.3 ms and a duty cycle of ≤ 20%. The diode lasers have a maximum optical output power of 70 W and a center wavelength of 808-938 nm with a typical spectral bandwidth of 3 nm. The typical slope is 0.8-0.7 W/A, and the maximum operating voltage is 2.2 V. The diode lasers are equipped with a power monitor (Infineon, SFH 229) and a temperature sensor (PT 100 and PT 1000).

They are connected in series with integrated TECs, and the cold side is at a maximum of 30 °C. The maximum cooling power is 346 W, and the maximum TEC voltage and current are 49.2 V and 11.3 A, respectively. The diode lasers are designed to be mounted via thermally conductive foil on a cooled surface and are intended for use in a non-condensing atmosphere. The expected lifetime of the diode lasers is greater than 1 GShot.
