1940/1950nm CW Fiber Laser

Product Description:

Connet 2.0um (GHz) series of CW fiber lasers use the Master Oscillator Power-Amplifier (MOPA) structure or the direct resonator cavity structure design to achieve the high power output. The generally adopted pumps are the semiconductor or fiber lasers in the bands of 793nm and 1570nm. The output polarization can be linear or random. This laser is suitable for the applications of device testing, medical treatment, remote sensing, LiDAR and mid-infrared pumping, etc. with the typical operating wavelengths of 1908nm, 1940nm, 1950nm, 2004nm and 2050nm, etc.


The 2.0um (GHz) series of CW fiber lasers employ the microprocessor-based control system with stable performance and maintenance-free operation. The benchtop laser can display the output power, the temperature and other working status in real time through the LCD on the front panel, and also can provide the alarm information in time. This laser system is with clear interface and easy operation.
