Abstract

Continuous-wave tunable laser operation of direct diode-pumped Cr⁴⁺:Mg₂ SiO₄ (Cr:forsterite) and Cr⁴⁺:Ca₂GeO₄ (cunyite) crystal were demonstrated. Diode-pumped Cr:forsterite was tunable over the 1236–1300-nm spectral range. The maximum output of 10 mW was measured at 1260 nm for 640 mW of pump power absorbed by the crystal. Diode-pumped laser operation of cunyite was also demonstrated over the 1390–1475-nm range. Free-running 20-mW output was centered at 1410 nm.
