STBWT series Fiber Coupled Diode Lasers

Our STBWT series fiber-coupled diode laser can be divided into two categories:

Single Emitter Diode Laser

Single emitter diode lasers can provide multi-wavelength covering 405nm to 976nm, output power from 2mW to 10W. Mainly used in the area of fiber laser pumping ,computer to plate(CTP), DPSS laser pumping, medical use, aiming beam, industry etc. For different application, varieties of packages with optional functions of aiming beam, photo detector, TEC, fiber detector, thermistor and other functions are available.

Mult-Single Emitter Diode Laser

Multiple single emitter diode lasers build upon the foundation of multi-emitter coupling technology, to obtain high power and high brightness diode laser. Varieties of packages with optional functions of aiming beam, photo detector, TEC, fiber detector, thermistor and other functions are available. Multi single emitter diode lasers have great advantages in high reliability and high performance. In multi-single emitter diode laser, BWT have patented many improved optical designs. And these compact packages and commercially recognized formats allow easy integration into the existing products.

Multi single emitter diode lasers include wavelengths from 635nm-976nm, output power from 1.6W-200W.
