AMETIST BB-01
BroadBand CW Dye Laser
The AMETIST BB-01 consists of a three-mirror linear cavity with a one-,
two- or three-plate
Birefringent
Filter. The mirrors provides the high conversion
efficiency and the wide working spectral range for the corresponding dyes.
A micrometer controlled rotating the birefringent plate(s) on an axis
normal to it tunes the wavelength radiation. By observing the calibrated
micrometer screw markings, it is possible to reset the center of line radiation
to within 0.1 nm.
The AMETIST BB-01 was designed for high amplitude stability and
repeatable performance without frequent alignment and adjustment.
Stable three invar rod cavity provides excellent reproducibility of alignment
from the start to start.
The typical linewidth for AMETIST BB-01 with a 1-, 2- or 3-plate plate
birefringent filter is 500 GHz, 200 GHz or 40 GHz accordingly.Output Power Specifications
