Tunable laser operations in a Nd-doped SrLaAlO 4 crystal

Tunable laser operations in a disordered crystal, Nd:SrLaAlO 4 , were experimentally reported. The maximum tuning range of 32 nm from 1063 to 1095 nm was achieved with a birefringent filter (Lyot filter). The maximum output power was 1.66 W at the center wavelength of 1075.5 nm, giving an optical-to-optical efficiency of 30%. The output power over 50% of the tuning range was greater than 0.6 W. The special spectral lines, such as 1073, 1080 and 1083 nm, have a potential application in the field of atom and molecular spectroscopy.
