DS3 Semiconductor Laser System
The DS3 Semiconductor Laser System is a high-power, fiber-coupled diode laser system developed by BWT Beijing Ltd., a global leader in laser solutions founded in 2003. The system is available in 915nm and 976nm center wavelengths with output power options of 200W (DS3-51516-LD, air-cooled) and 300W (DS3-51514-LD, water-cooled). It delivers laser output through a 200μm core diameter fiber with 0.22 numerical aperture and SMA905 connector. Featuring constant current drive, the system supports CW, pulse and single-pulse working modes with flexible control via touch screen, RS232 and I/O interfaces. With a compact M-size chassis (387×373×153mm), excellent power stability of ±3% over 5 hours, and a built-in 635nm red pilot beam, the DS3 series provides a reliable, integrated laser source for industrial welding and processing applications.
