1550nm Peak Power 20W Long Pulses Laser Quasi-CW SM Fiber Laser System Bechtop FLH-QCW-1550-20-SM-B3
This device delivers high-power quasi-continuous (long-pulse) laser output at a wavelength of 1550 nm, delivering 10 joules of energy in a 500ms pulse duration or 20 millijoules in a 1ms pulse duration. Its maximum average output power is ≥10 watts, and its peak power is ≥20 watts. The output is coupled to a single-mode fiber and features excellent beam quality, high pulse energy, adjustable frequency, and stable spectrum and power. Its desktop design offers easy operation and a simple, intuitive control interface, making it suitable for applications such as medical aesthetics and scientific research.
