Room-temperature diode-pumped continuous-wave SrY4(SiO4)3O: Yb3+, Er3+ crystal laser at 1554 nm

Abstract

Continuous-wave (cw) laser operation at room temperature of an Yb3+, Er3+ doped oxyapatite single crystal SrY4(SiO4)3O pumped at 980 nm by an InGaAs diode laser has been achieved around the eye-safe laser wavelength of 1554 nm.
