Optical Parametric Amplifiers (OPAs) are nonlinear optical devices allowing the generation of widely tunable ultrashort pulses, and also providing, if suitably designed, very broad gain bandwidths. This chapter reviews the principles of ultrashort pulse OPAs, focusing in particular on the generation ...
This property is essential for designing compact and high power four-wave optical parametric amplifiers. The proposed four-wave optical parametric amplifica- tion methodology could be adapted to virtually all transpar- ent media: solids, liquids, and gases and throughout a variety of wavelengths, ...

optical parametric amplifiersThe development of ultrafast and intense laser sources has paved the way to the study of laser鈥搈atter interaction in the strong-field regime, where the amplitude of the laser field becomes comparable to the Coulomb field seen by electrons in the proximity of their ...
(EMI 9658 BM and Hamamatsu 5509‐72). Temperature-dependent measurements were performed with a cryostat working in a closed cycle cooling system. The PL lifetime measurements were performed using a Hamamatsu streak camera with an OPerA‐Solo optical parametric amplifier and a Coherent Libra ...
which is in electrical contact with the sample surface. Pump and probe laser pulses are generated from a regenerative amplifier system running at 200 kHz and several optical parametric amplifiers (OPAs) working at 200 kHz (PHAROS, internal OPA, Orpheus-N-2H, Orpheus-N-3H by Light Conversio...
The experimental setup was as described before18. Briefly, the output of Ti:Sapphire regenerative amplifier (Spitfire PRO, Spectra Physics, 4 W, 70 fs) was divided between two optical parametric amplifiers (Topas-C, Light Conversion). One of the parametric amplifiers was equipped with nonco...
They also are used to pump optical parametric amplifiers in short-pulse tunable applications, such as pump-and-probe spectroscopy and four-wave mixing. The ease of operation of all-in-one units has brought amplified Ti:sapphire systems out of academic environments and into more application-...
While three-photon excitation systems based on optical parametric amplifiers (OPAs) are available, they are prohibitively expensive and highly inefficient — providing less than 10% total conversion efficiency. Work is underway to develop commercially viable alternatives that are compatible with existing mi...
(Astrella, Coherent), which outputs 800 nm pulses at a repetition rate of 4 kHz, with a nominal temporal width of 35 fs. The output of the amplifier is divided and passed onto a pair of optical parametric amplifiers (OPAs; TOPAS Prime, Coherent), which produce near-infrared (NIR)...
