DK Photonics 1550/1565nm Wavelength Quasi-CW Fiber Laser (Long Pulses Laser) can achieve high-power laser quasi continuous (long pulse) laser output with wavelengths of 1550 or 1565nm, providing 10 joules of energy within 500ms pulse time or 20 millijoules of energy within 1ms pulse time. The maximum average output power of the laser is ≥ 10 watts, and the maximum peak power is ≥ 20 watts. The output method is single-mode fiber coupling, which has the characteristics of good beam quality, high pulse energy, adjustable frequency, stable spectrum and power. The desktop design is easy to operate, with a simple and intuitive control interface, suitable for medical beauty, scientific research experiments, and other uses.
