High-repetition-rate femtosecond optical parametric oscillator-amplifier system near 3 mm
An ultrafast laser system for the chemically important 3-mm spectral region has been constructed by means of noncritically phased-matched KTiOPO4 optical parametric gain elements. An optical parametric oscillator, synchronously pumped by a mode-locked Ti:sapphire oscillator, generates high-quality seed pulses for an optical parametric amplifier. The optical parametric amplifier, pumped by a hig...
متن کاملGeneration and characterization of tunable mid-infrared femtosecond pulses
In this Chapter we describe the design of an optical parametric amplifier that allows the generation of infrared laser pulses suitable for ultrafast nonlinear spectroscopy on the OH-stretching mode of water molecules. Mid-infrared femtosecond pulses, tunable in the range of 2800-3800 cm with sub-100 fs duration and ~15 μJ energy are produced by an optical parametric amplifier driven at 1 kHz by...
متن کاملTunable spectral interferometry for broadband phase detection by use of a pair of optical parametric amplifiers
We demonstrate tunable, single-pulse spectral phase measurement of broadband ultrafast signals by linear spectral interferometry. The approach is based on a coherently coupled pair of optical parametric amplifiers (OPAs). The first amplifier is the source of a signal pulse that is coupled into a nonlinear medium, where the pulse generates a broadband signal by nonlinear interactions; the second...
متن کاملParametric generation and characterization of femtosecond mid-infrared pulses in ZnGeP2.
Ultrafast mid-infrared (IR) coherent radiation plays an important role in strong-field physics, wherein the use of longer wavelengths has reduced the optical intensities needed to drive light-matter interactions by orders of magnitude in comparison to near-IR radiation. Optimizing parametric interactions for generation and characterization of mid-IR pulses is an enabling step for those applicat...
متن کاملGeneration of fs laser pulses from a ps pulse-pumped optical parametric amplifier with a beat-wave seed signal
We describe a method of ultrashort-pulse and ultrafast-pulse-train generation through optical parametric amplification of a laser beat wave. Numerical simulation shows that 250-fs laser pulses at 1.55 lm are generated from a beat-wave seeded optical parametric amplifier pumped by a 30-ps laser at 1064 nm. The pulse compression is attributable to sideband generation and parametric amplification ...
