Polyatomic molecules in condensed phases possess a manifold of vibrations that are of intra- and/or intermolecular character (section ).Intramolecular vibrations in a frequency range from approximately 30– THz (– cm −1) have been studied extensively by nonlinear vibrational spectroscopy in the femto- to picosecond time domain.. Two-dimensional infrared (2D-IR. The Laser Spectroscopy Conference held at Vail, Colorado, June , was in certain ways the first meeting of its kind. Var ious quantum electronics conferences in the past have covered non linear optics, coherence theory, lasers and masers, breakdown, light scattering and so on. However, at Vail only two major themes were developed - tunable laser sources and the use of lasers in.

Generation of far-infrared radiation by optical rectification of picosecond light pulses and by mixing of two tunable dye lasers. Theoretical study of coherent phonon generation by optical means in a one-dimensional superlattice. Three investigations of difference frequency generation (DFG) of far-infrared radiation by optical mixing are described, i.e., a theory of DFG by monochromatic, focused Gaussian pump laser beams, a theory of DFG by a picosecond pump laser pulse, and an experiment using ruby-pumped dye lasers.
obtained by these schemes is limited for each gas and laser combination and is not continuously tunable. Molecular gas lasers using gases such as HCN, CH 3 F, or methanol provide a number of discrete wavelengths in the wavelength region beyond 30 µm and extending to longer than µm.
Most of these lasers are optically pumped by pulsed CO 2 lasers and emit pulses in the microsecond time. We report efficient generation of picosecond pulses in the near-and mid-infrared in the new nonlinear material CdSiP(2) pumped at mu m by an amplified mode-locked Nd: YVO(4) laser at kHz.
Frequency upconversion of laser pulses at μm to those at μm was measured in the presence of Nd:YAG laser pulses based on difference-frequency generation in a mm-long GaSe crystal.

Typical synchronously pumped OPOs have a picosecond or femtosecond mode-locked laser as a pump source, such as a 1-μm neodymium-doped laser or a titanium–sapphire laser.
Their average pump power is between a few hundred milliwatts and a few watts, the pulse repetition rate is between MHz and 1 GHz, and the power conversion efficiency is.

After the pulse compressor consisting of four gratings, we obtained compressed laser pulses with an energy of 83 J and the pulse duration of fs, producing PW laser pulses with the low energy fluctuation of % (rms).
Consequently, we successfully upgraded one of the PW laser beamlines to the 4 PW, 20 fs beamline. High-power terahertz (THz) generation in the frequency range of –10 THz has been a fast-developing research area ever since the beginning of the THz boom two decades ago, enabling new technological breakthroughs in spectroscopy, communication, imaging, etc.
