Dual-Wavelength Operation at 607 nm and 640 nm with the Same Threshold and Slope Efficiency in Pr<sup>3+</sup>:LiLuF<sub>4</sub> Crystal

Dual-Wavelength Operation at 607 nm and 640 nm with the Same Threshold and Slope Efficiency in Pr<sup>3+</sup>:LiLuF<sub>4</sub> Crystal

A dual-wavelength (DW) Pr<sup>3+</sup>:LiLuF<sub>4</sub> (Pr:LLF) laser with the same threshold and slope efficiency was achieved for the first time. We theoretically deduced the conditions for obtaining the same threshold and slope efficiency of the DW operation, and experim...
