Infrared lasers include DPSS (diode-pumped solid-state) laser and diode laser. The laser head comes with cooling and precise temperature control system, and power supply comes with overcurrent and overheating protection function. CNI lasers have stabilized power, easy operation, reliable performance and long lifetime. The laser products include 5 series: high energy, high power, high stability, low noise and single longitudinal mode laser. Free space or fiber-coupled (SM fiber, MM fiber, homogenization fiber) output available.
