“…It was discovered that ultrabroadband spectra and tunable ultrashort pulses could also be generated in various transparent bulk media using FWM process [ 25 – 52 ]. In the case of solid-state bulk media, due to high material dispersion, phase matching can be obtained only if the two pump beams have a finite crossing angle in the media.…”

We have reviewed the generation and amplification of wavelength-tunable multicolored femtosecond laser pulses using cascaded four-wave mixing (CFWM) in transparent bulk media, mainly concentrating on our recent work. Theoretical analysis and calculations based on the phase-matching condition could explain well the process semi-quantitatively. The experimental studies showed: (1) as many as fifteen spectral up-shifted and two spectral down-shifted sidebands were obtained simultaneously with spectral bandwidth broader than 1.8 octaves from near ultraviolet (360 nm) to near infrared (1.2 μm); (2) the obtained sidebands were spatially separated well and had extremely high beam quality with M2 factor better than 1.1; (3) the wavelengths of the generated multicolor sidebands could be conveniently tuned by changing the crossing angle or simply replacing with different media; (4) as short as 15-fs negatively chirped or nearly transform limited 20-fs multicolored femtosecond pulses were obtained when one of the two input beams was negatively chirped and the other was positively chirped; (5) the pulse energy of the sideband can reach a μJ level with power stability better than 1% RMS; (6) broadband two-dimensional (2-D) multicolored arrays with more than ten periodic columns and more than ten rows were generated in a sapphire plate; (7) the obtained sidebands could be simultaneously spectra broadened and power amplified in another bulk medium by using cross-phase modulation (XPM) in conjunction with four-wave optical parametric amplification (FOPA). The characterization showed that this is interesting and the CFWM sidebands generated by this novel method have good enough qualities in terms of power stability, beam quality, and temporal features suited to various experiments such as ultrafast multicolor time-resolved spectroscopy and multicolor-excitation nonlinear microscopy.

“…This offers an additional degree of freedom in frequency conversion. Indeed, by taking an advantage of this possibility, generation of UV laser harmonics by means of fourwave difference frequency mixing [20] and UV-tunable 30-fs pulses by parametric frequency up-conversion of visible pulses [21] was demonstrated. More recently, a similar technique was applied in the near-IR spectral range, yielding broadly tunable sub-30 fs pulses from fused silica based four-wave optical parametric amplifier [22].…”

We propose two methods for ultrashort pulse parametric visible-to-infrared frequency conversion, that are directly applied to extend the tuning range of a commercial Ti:sapphire laser-noncollinear optical parametric amplifier system. The first method is based on broadband noncollinear four-wave optical parametric amplification in fused silica, and the second is based on cascaded three-wave parametric interaction in a single BBO crystal. The proof-of-principle experiments demonstrate generation of sub-30-fs, ∼20 µJ pulses, broadly tunable across the infrared (1-3 µm) spectral range.
