FL-1940-CW1940 nm infrared high-power fiber laser
1940 nmThe FL-1940-CW is a 1940 nm continuous-wave fiber laser. Pump energy is supplied to an active fiber, which guides the light and provides optical gain as it propagates. Output coupling then delivers the amplified beam to the experiment. Continuous-wave operation provides a sustained beam for experiments that need steady illumination.
