K878BNLRN-65.00W 878.6nm 65W High Power Wavelength-Stabilized Semiconductor Laser
The K878BNLRN-65.00W is a high-power wavelength-stabilized fiber-coupled semiconductor laser module delivering a minimum 65W output at 878.6±1nm. It uses a 200μm core / 220μm cladding fiber with 0.22NA, a 1.5m fiber length and an SMA905 connector. The module provides a narrow 0.5nm FWHM spectrum, 0.03nm/°C wavelength temperature coefficient, 48% typical electro-optical efficiency and 1020nm~1200nm anti-reflection protection with 30dB typical isolation. Typical data are measured at 65W output and 25°C.
