SPL MN81G2 is a passively cooled diode laser bar with 50W cw output power at 808nm. It features a passive heat sink design that does not require cooling water. It is suitable for continuous wave (cw) and quasi-continuous wave (qcw) operation. The laser bar utilizes highly reliable semiconductor material with a minimum lifetime of 10,000 hours, typically exceeding 50,000 hours. It has low thermal resistance, low smile (<2.5 μm), and low mechanical tolerances. The applications include pumping of solid state lasers, direct industrial applications (soldering, surface treatment, etc.), medical applications, and printing applications.
