We have studied the simultaneous dual-wavelength laser operation of the X-cut, Y-cut, and Z-cut Yb3+:Ca4LaO(BO3)3 crystals for the first time to the best of our knowledge. We analyzed the dual-wavelength laser output power and emission spectra under several output coupler transmittances. The stable dual-wavelength lasers were generated by adjusting the laser elements. A dual-wavelength laser output power 2.46 W was obtained with a slope efficiency of 67.5% by employing the Y-cut crystal at 1029 and 1036 nm. The two wavelengths had nearly the same relative intensity. The two different emission wavelengths were found to change with crystal direction and output coupler transmittance. This laser has a possible application as the laser source in the generation of different terahertz waves.
