AB  - We demonstrate versatile dual-wavelength synchronous mode-locking of a diode-pumped Cr:LiSAF laser for the first time. Two-color mode-locked operation is achieved by using intracavity birefringent filters (BRFs) or etalons as frequency-selective elements. Using filters with different thicknesses and hence different free spectral ranges (FSRs), two-color mode-locking wavelength separation could be adjusted between 1 and 9 nm, with corresponding beating frequencies in the 0.4-3.5 THz range. Moreover, the central wavelength of the two-color output could be tuned smoothly between 840 nm and 875 nm, only limited by the bandwidth of the semiconductor saturable absorber mirror (SESAM) used for mode-locking. The method, which enables easy adjustment of central wavelength and beating frequency of dual-wavelength operation, is suitable for use in other laser gain media as well.
