A discretely tunable dual-wavelength multi-watt Yb:CALGO laser

A discretely tunable dual-wavelength diode-pumped Yb:CALGO laser using a single birefringent filter (BRF) plate which covered a wavelength range of approximately 1020–1070 nm was demonstrated. A detailed study was conducted for BRF plates with thickness of 0.5, 2, 4 and 6 mm using different output c...

Description
Summary:A discretely tunable dual-wavelength diode-pumped Yb:CALGO laser using a single birefringent filter (BRF) plate which covered a wavelength range of approximately 1020–1070 nm was demonstrated. A detailed study was conducted for BRF plates with thickness of 0.5, 2, 4 and 6 mm using different output couplers. This simple design was capable of delivering multi-watt dual-wavelength output power and the frequency offset discretely varied from approximately 1.3 to 12.5 THz. The maximum dual-wavelength output power was 4.1 W using a 6-mm-thick BRF plate with 5% output coupler.
