RESUMO

The present work shows the development of a color Center laser for spectroscopy application. It is a CW laser which uses an X-type cavity with two astigmatically compensated intracavity spherical mirrors. The laser can be converted to a ring laser. The used active medium was a KCl:Li+ single crystal with a FA (II) centers and the pumping source was an Ar+ laser (λ= 514nm, 700mW). Pump power at threshold was measured to be 120mW. The tuning range was 2.56< λ < 2.82 μm and the slope efficiency was 2,8%. To test the color center laser we measured intracavity spectra of KCl: Li+: NO-2: NO-3 and KBr:OH- single crystals.
