Diode-pumped solid-state lasers using novel Yb:LaF3 and Tm,Ho:LaF3 crystals as laser gain materials are demonstrated herein. The Yb:LaF3 and Tm,Ho:LaF3 crystals were grown using the Bridgman method. By matching their absorption bands, continuous-wave laser operations were achieved for the first time. The Yb:LaF3 laser obtained a maximum average output power of 1.19 W with dual wavelengths of 1028 nm and 1033 nm. The maximum average output power and slope efficiency of the Tm,Ho:LaF3 laser were 574 mW and 18.5%, respectively. The Tm,Ho:LaF3 laser exhibited two peaks at 2043 nm and 2048 nm. Both the Yb:LaF3 and Tm,Ho:LaF3 crystals were confirmed to be laser gain materials.
