title: Spectral properties and laser performance of Ho:Sc₂SiO₅ crystal at room temperature.
abstract: Holmium doped scandium silicate (Ho:SSO) bulk crystal grown by Czochralski technique is reported. The absorption cross section of 4.8 × 10(-21) cm2 at pumping wavelength 1940 nm and emission cross section of 5.56 × 10(-21) cm2 at lasing wavelength 2112 nm were calculated, respectively. Lifetime was measured to be 1.51 ms at 300 K and 0.92 ms at 77 K. Continuous-wave laser was operated by using a diode-pumped Tm:YAP laser as pump source with central wavelength of 1940 nm. Output power of 385 mW at 2112 nm was primarily obtained.
