K785AFLWN-0.600W 785nm 600mW Butterfly Packaged Semiconductor Laser
The K785AFLWN-0.600W from BWT is a 785nm 600mW butterfly-packaged fiber-coupled semiconductor laser. It delivers 600mW output power through a 105μm core / 125μm cladding, 0.22NA fiber with an FC connector, featuring a narrow spectral width (<0.1nm FWHM) and low wavelength drift (0.01nm/°C). The 14-pin butterfly package integrates a TEC, thermistor and monitor photodiode (PD) for precise temperature control and stable power monitoring, ensuring reliable performance in demanding applications.
