ABSTRACT
A high-power tunable dual-wavelength composite external cavity architecture obtained by means of a holographic grating and a volume Bragg grating is proposed and demonstrated. The tunable frequency difference of the dual-wavelength output is from 0.41â
THz to 3.89â
THz. We obtain an output power of 2.1â
W when the frequency difference is 1.86â
THz. The side-mode suppression ratio of more than 29â
dB is suppressed over the entire tunable dual-wavelength output range. The two corresponding wavelengths of the dual-wavelength output basically maintain the same intensity with the smallest power difference of only 0.10%.
