“…The first experimental demonstration of the SC generation in sapphire dates back to 1994 [201], revealing sapphire as a long sought solid-state material to replace the liquid media commonly used at that time, putting the technology of femtosecond optical parametric amplifiers on all-solid state grounds (see also [202] for more details). Since then, sapphire became a routinely used nonlinear medium for SC generation with Ti:sapphire driving lasers, providing a high quality seed signal that boosted the development of modern ultrafast optical parametric amplifiers [45,47,203].…”

Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads to a specific propagation regime, termed femtosecond filamentation, which in turn produces dramatic spectral broadening, or superbroadening, termed supercontinuum generation. Femtosecond supercontinuum generation in transparent solids represents a compact, efficient and alignment-insensitive technique for generation of coherent broadband radiation at various parts of the optical spectrum, which finds numerous applications in diverse fields of modern ultrafast science. During recent years, this research field has reached a high level of maturity, both in understanding of the underlying physics and in achievement of exciting practical results. In this paper we overview the state-of-the-art femtosecond supercontinuum generation in various transparent solid-state media, ranging from wide-bandgap dielectrics to semiconductor materials and in various parts of the optical spectrum, from the ultraviolet to the mid-infrared spectral range. A particular emphasis is given to the most recent experimental developments: multioctave supercontinuum generation with pumping in the mid-infrared spectral range, spectral control, power and energy scaling of broadband radiation and the development of simple, flexible and robust pulse compression techniques, which deliver few optical cycle pulses and which could be readily implemented in a variety of modern ultrafast laser systems.

“…crystals and glasses) has been the subject of intensive investigations [3]. The widely spread practical applications of the so-generated SC pulses are, among others, femtosecond time-resolved spectroscopy [4], spectral interferometry [5], or their use as seed pulses for optical parametric amplifiers [6,7].…”

Diffractive optics for spectral control of the supercontinuum generated in sapphire with femtosecond pulses

Abstract:We propose the use of kinoform diffractive lenses to focus near infrared femtosecond pulses in sapphire crystals for supercontinuum generation. It is shown that a strongly peaked structure appears in the blue region of the supercontinuum spectra. The central wavelength of this peak can be easily controlled by simply changing the lens-crystal distance. Moreover, when compared with the supercontinuum generated with a refractive lens in analogous conditions, the spectral extension of the sogenerated continuum is larger. Our results were corroborated for sapphire plates with different thicknesses as well as in other transparent dielectrics such as fused silica. ©2011 Optical Society of America

“…Despite recent successful applications of solid state materials to generate femtosecond WLG and to use it for a seed pulse of OPA, [30][31][32][33] none of the solid state materials yielded stable WLG, because the damage threshold was so close to ͑or even lower than͒ the threshold of efficient WLG that immediate burning of the materials took place upon irradiation of the pump pulse. In contrast, both H 2 O and D 2 O could generate white light continuum in a stable manner.…”

Two systems of widely tunable light sources for picosecond time-resolved resonance Raman (ps-TR3) spectroscopy have been constructed using a 1 kHz ps-Ti:sapphire laser/regenerative amplifier system. Performance of the systems was examined in terms of pulse duration, spectral width, pulse energy, and shot-to-shot stability. One system, consisting of white light continuum seeder and β-barium borate optical parametric amplifier, demonstrated tunability in the 500–660 nm range with 1.3–2.1 ps pulse duration and 15 μJ pulse energy. The other system, consisting of a lithium triborate optical parametric generator in type II noncritical phase matching configuration and β-barium borate optical parametric amplifier, was found to yield visible pulses as high as 18 μJ with 1.5–2.4 ps of pulse duration in the 520–630 nm region. The shot-to-shot stability of generated pulses is less than 10% for both systems. Capability of the present systems is demonstrated by observing ps-TR3 spectra of nickel octaethylporphyrin in coordinating and noncoordinating solvents.
