Multi-watt dual-wavelength operation of a diode-pumped Yb:CALGO laser was achieved by introducing a thin birefringent filter (BRF) plate into a standard laser cavity. A BRF plate with a thickness of 0.5 mm was capable of generating a dual-wavelength output with a frequency offset of 1.31 THz (equivalent to a wavelength separation of 4.8 nm). The output power of the dual-wavelength laser at 1044.7 nm and 1049.5 nm was 2.6 W. The developed dual-wavelength Yb:CALGO laser with multi-watt output power is an attractive and cost-effective candidate for generation of THz radiation and dual-wavelength mode-locked lasers.
