2026-06-08 Optical Properties, and Continuous-Wave Laser Performance of a Novel Yb:Ca(Y,Lu)AlO4 Disordered Laser Crystal doi:10.57760/sciencedb.38811 en A novel Yb:Ca(Y,Lu)AlO4 (Yb:CYLA) disordered laser crystal with the highest full width at half maximum (FWHM) of emission cross-section spectra reported for Yb-doped laser crystals until now was directionally grown using the Czochralski method. Its physical and chemical properties and polarized spectra were investigated. The maximum absorption cross-sections were 7.98 × 10-20 cm2 (π-polarization) and 2.67 × 10-20 cm2 (σ-polarization), and the peak emission cross-sections were 0.72 × 10-20 cm2 (π) and 0.93 × 10-20 cm2 (σ). A bandwidth of 94 nm in the σ-polarization emission spectra was observed. A continuous-wave laser experiment was performed, and a maximum output power of 3.6 W was achieved with a slope efficiency of 23.7%. The Yb:CYLA disordered laser crystal is proved to be a promising material for ultrafast lasers.  laser crystal; Yb:CYLA; continuous-wave laser Shi Li PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
