Abstract

We obtained, what is to our knowledge, record tuning from an intracavity-pumped gain-switched Cr 2 + : Zn Se laser. In the experiments, a polycrystalline Cr 2 + : Zn Se sample with an absorption of about 43% at 1570 nm was used to minimize reabsorption losses at the lasing wavelengths below 2000 nm . By placing the gain medium inside the cavity of a pulsed KTP optical parametric oscillator (OPO) operating at 1570 nm , smooth, continuous tuning was achieved in the 1880 3100 nm range with four different sets of cavity optics. As high as 145 mW of average laser output power was obtained at 2365 nm with 1.2 W of intracavity OPO power.
