      abstract     = {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.},
