[Radiant Dyes Laser & Acc. GmbH]
ca-standing wave Dye-Laser and Ti:Sa Laser


This dye laser is based on our exchange unit for the Coherent 699 ring laser RDU 10 (nozzle holder and pump mirror adjustment). We paid attention to it that the laser is easy to handle. 

By an adjustment with micrometer screws a very high reproducibility is guaranteed. The laser is mounted on a 50 mm invar rod and the dimensions allow a later installation of the etalon for single mode operation.

It consists of a 3-mirror-resonator, wavelength tuning is done by rotation of the Lyot-filter.
