. Anti monitor arrowverse On. We focus on high-energy ultrashort pulses at wavelengths widely separated from those of the pump and find that within this regime a number of simple properties describe the essential phase and gain dynamics. In most cases parametric amplifiers are used for pulses which may be nanosecond pulses from Q-switched lasers or ultrashort pulses from mode-locked lasersWith the high pump intensities achievable with pulses the parametric gain can be very high sometimes more than 80 dB within a few millimeters of crystal material.
Cerullo Design criteria for ultrafast optical parametric amplifiers J. With diode-pumped Yb laser technology reaching maturity average power scaling of multi-GW few-cycle short-wave and mid-infrared MIR optical parametric amplifiers OPAs to the 100-W level has become a reality. Optical parametric amplifiers OPAs exploit second-order nonlinearity to transfer energy from a fixed frequency pump pulse to a variable frequency signal pulse and represent an easy way of tuning over a broad range the frequency of an otherwise fixed femtosecond laser system.

Few-optical-cycle pulses tunable from the visible to the mid-infrared by optical parametric amplifiers. The authors describe another unique feature of OPAs namely the capability to generate under suitable conditions pulses with a constant carrier-envelope phase. These advances together with the discovery of new nonlinear optical crystals have fostered the introduction of ultrafast optical parametric amplifiers as a practical.
For a CW seed this is the chirp-matched case. Well established commercially available oxide crystals offer a relatively straightforward solution in the 14-4-μm spectral range. In recent years optical parametric chirped-pulse amplification OPCPA has emerged as a powerful tool for the generation.

Responsible for the CAPEM ultrafast laser facility which includes a Coherent Ti-sapphire oscillator and a regenerative amplifier pumped by a CW Ar laser as well as a visible and an infrared optical parametric amplifier and several frequency doubling and tripling setups.

OPAs can also act as broadband amplifiers transferring energy from a narrowband. The way an OPA is implemented depends on its architecture the characteristics of the laser source the amplification frequency range the.

Two-color pump-probe system broadly tunable over the visible and the near infrared with sub- temporal resolution. Over the last decade there have been spectacular developments in ultrafast laser technology due to the introduction of solid state active materials and of new mode-locking and amplification techniques.

We theoretically investigate methods of controlling pulse generation in normal-dispersion fiber optical parametric chirped-pulse amplifiers. Here we formalize it in terms of the pump and fiber parameters for the case of four-wave-mixing with a fixed sideband frequency. We demonstrate that using two nonlinear crystals cut for different phase matching types in an optical parametric amplification stage suppresses back-conversion which results in considerable improvements of conversion efficiency and signal beam quality.
