Description

Laser Attenuator 48AT-Comp is used for reproducible and precise reduction of the power output by the laser. It can be connected to the multicube system. The collimated laser beam is constricted by a precision ball transported by a scaled micrometer screw. A separate subsequent single-mode fiber coupling is used as a mode filter.
This mechanically stable attenuation method allows the precise and reproducible setting of the laser power output over a wide range (typically 1.5 to > 60 dB). Unlike a power regulation by modulation of the laser current, the wavelength and polarization status of the laser beam are preserved.

A reproducible power attenuation is only assured for single-mode fibers that have a Gaussian intensity profile.
