Description
The narrow-band diode lasers from CrystaLaser feature an internal optical feedback to force the laser diode which normally operates in several modes onto a single longitudinal mode. The result is the laser diode operates in a narrow band with a coherence length of up to 5 m. Thanks to a feature that stabilizes the temperature of the laser head and a low-noise controller, a high degree of long-term stability and low noise levels can be achieved. Beam forming optics guarantee an almost perfect circular beam with a very good M2 value.
