Abstract:
The primary goal of this research is to obtain laser
radiation from two dyes, (Coumarin500 & Rhodamine 6G),
study the resulted laser properties and study the effect of
different solvents on the laser output. In this work, two dyes
(Coumarin500 & Rhodamine 6G) were dissolved each
separately in three different solvents (acetone, methanol
and ethanol) with two concentration levels values (1.4 & 1.6
g/l). Optical properties of dyes solvents and solutions
(transmission, absorption and emission) were successfully
determined. These solutions optically pumped by nitrogen
laser
of
wavelengths
(337nm)
using
Hansch
cavity
configuration to produce laser.
In the case of the first Dye, (Coumarin 500) no laser
radiation obtained for all solutions (acetone, methanol and
ethanol) in all concentrations, While trials with the second
dye (Rhodamine 6G), we produced laser successfully when
the dye dissolved in all solvents used in this work with the
concentration 1.6g/l.
