Narrow-band SLM diode lasers: Compact diode lasers with a long coherence length
Laser 2000 is now exclusively offering CrystaLaser narrow-band diode lasers in a new compact design. A cost-effective technology produces coherence lengths of up to 100 m and MHz line widths.
SLM diode lasers from CrystaLaser in a new, compact design
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 100m. 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.
The available wavelengths range from UV at 375nm through the visible spectrum to near infrared at 1552nm. The optical power lies between 5 mW and 800 mW.
Narrow-band diode lasers are typically used in the following areas:
. Interferometry
. Raman spectroscopy
. Raman microscopy
. Sensor technology
. Analytical devices
