Abstract

A new silicate laser crystal, Tm:Lu₂SiO₅ (Tm:LSO) crystal, has been obtained by the Czochralski technology. Absorption spectra and fluorescence (un-polarized) spectra of Tm:LSO have been measured at room temperature. Parameters such as Judd-Ofelt intensive parameters, oscillator strength, spontaneous radiation rate, fluorescence lifetime, integrated absorption cross-section, integrated emission cross-section were calculated by Judd-Ofelt theory. Intensive parameters were calculated to be Ω₂ = 9.1355 × 10^-20 cm², Ω₄ =8.4103 × 10^-20 cm², Ω₆ = 1.5908 × 10²⁰ cm². Some main emission peaks exist around 1.9μm, corresponding to ³F₄ → ³H₆ transition. Fluorescence lifetime and integrated emission cross-section, corresponding to ³F₄ → ³H₆ transition, were calculated to be 2.03 ms and 5.81 × 10^-18 cm², respectively. Laser actions have been obtained by use of Tm:LSO crystal at the temperature of 77 K. The central laser wavelength of 1960 nm and pumping threshold of 2.13 kW/cm² were obtained.
