摘要： Fundamental-wavelength pulses from a fiber a laser are divided into three or more pulse portions and the three or more portions are separately amplified. Two or more of the amplified fundamental-wavelength pulse-portions are combined and frequency-doubled. The frequency doubled portion is sum-frequency mixed with one or more of the other amplified fundamental wavelength pulse-portions to provide third-harmonic radiation pulses.

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).

摘要： Master oscillator power amplifier (MOPA) apparatus includes two seed-pulse sources coupled to a single fiber amplifier including one or more stages of amplification. One of the seed-pulse sources is a single-mode source generating pulses having a duration selectively variable between about 0.1 ns and 10 ns. The other seed-pulse source is a multi-mode source generating pulses having a duration selectively variable between about 1 ns and 10 μs. Selectively operating one or the other of the seed-pulse sources provides that the apparatus can deliver pulses selectively variable in a range between about 0.1 ns and 10 μs.
