Description
With its unequaled narrow spectral linewidth (down to 1 kHz), Keopsys CEFL-KILO series lasers are especially designed for applications which required a high precision such as LIDAR, atomic spectroscopy, atomic cooling...
CEFL-KILO series, are Erbium fiber doped lasers with low phase noise and low relative intensity noise. The system integrates an ultra low noise and narrow linewidth seed laser which is then amplified through our erbium fiber doped amplifier up to 15 W. These CW lasers come with linear or random polarization.
For application where the central emission line is critical, the CEFL-KILO offers the possibility to modulate it and to adjust the wavelength by changing the temperature.
The CEFL-KILO benefits from Keopsys VSP technology: reliability, robustness and maintenance free.
The CEFL-KILO series are available in benchtop for front face control or PC monitoring (RS232) with our B2V2 program, or in module for an easily integration.
