+If one would like to use the Sirah dye laser with Rhodamin B in the 620nm range it is recommended to use 0.9g/l (EG). This value was obtained experimentally as (according to the manual) the absorption of pump beam should be 0.85.  In this configuration the laser is much better workable in the 620nm range.

+**Update:** From the discussion with Matisse technician of the 24.08.2022 the EG should have a purity of >=99.5%. So the above mentioned EG is not suitable. Rather use this one here:\\
