Abstract
A femtosecond laser with a simple two-element cavity was built. This laser typically attained a repetition rate of 2.64 GHz with a pulse width of 115 fs at a center wavelength of 1540 nm. Output pulses were characterized by second-harmonic generation frequency-resolved optical gating. Alignment of the two-element cavity for mode-locked operation was easy; moreover, the cavity structure has the potential to produce an even higher repetition rate because one can miniaturize it simply by shortening a gain medium length.
