摘要
Pulses from a mode-locked Yb-doped laser (12) are spectrally broadened in an optical fiber (28), and temporally compressed in a grating compressor (32), then frequency-doubled (34) and used to pump an optical parametric oscillator (OPO) (40). The OPO output is tunable over a wavelength range from about 600 nm to about 1100 nm. Mode-locking in the Yb-doped laser (12) is accomplished with a SESAM (14) or by Kerr-lens mode-locking with a Kerr medium (82) and a hard aperture (84).
