Optical parametric amplification at critical wavelength degeneracy - a possible solution for multi-PW laser systems
نویسنده
چکیده
Optical parametric chirped pulse amplification (OPCPA) is one of the most powerful techniques for generating high-energy femtosecond laser pulses. Many efforts were devoted to get spectral-band amplification able to support sub-10-fs pulses. In the optical parametric amplification (OPA), broad gain bandwidths can be obtained if the wave-vectors mismatch, ∆k, slowly increases when the signal frequency varies around the phase-matching (PM) condition. The wave-vectors mismatch is given by a Taylor series expansion

High Power Hybrid Femtosecond Laser Systems
Hybrid femtosecond lasers combine the chirped pulse amplification (CPA) in laser media with optical parametric chirped pulsed amplification (OPCPA) in nonlinear crystals. A key feature of these systems consists in matching the parametric amplification gain bandwidth of nonlinear crystals to the spectral gain bandwidth of laser amplifying crystals. Gain bandwidths as broad as 150 nm can be obtai...
متن کاملUltra-broadband Optical Parametric Chirped Pulse Amplification By Two Broadband Pump Beams
Optical parametric chirped-pulse amplification (OPCPA) is suitable for a new approach to few-cycle, high-peak-power laser systems because of its broad gain bandwidth and large single-pass gain while maintaining negligible thermal load in a nonlinear crystal. In order to amplify ultrabroad bandwidth, various types of OPCPA schemes are proposed and demonstrated. Generally, non-collinear OPCPA (NO...
متن کاملHigh-contrast 1.16 PW Ti:sapphire laser system combined with a doubled chirped-pulse amplification scheme and a femtosecond optical-parametric amplifier.
Based on a combined scheme of doubled chirped-pulse amplification and a femtosecond noncollinear optical-parametric amplifier, a high-contrast femtosecond laser pulse with energy of up to 32.3 J has been generated by improving the gain efficiency and boosting the pump energy to 120 J in the final amplifier. Our measurements show that the contrast ratio of the main laser pulse is around 10(10) w...
متن کاملHigh harmonic generation with long-wavelength few-cycle laser pulses
We report the extension of hollow-core fibre pulse compression to longer wavelengths. High-energy multi-cycle infrared pulses are generated via optical parametric amplification and subsequently broadened in the fibre. 2.5-cycle pulses at the Signal wavelength (1.4 μm) and 1.6-cycle pulses at the Idler wavelength (1.8 μm) in the sub-millijoule regime have been generated. New compression schemes ...

An optical parametric oscillator (OPO) directly pumped by a diode laser is potentially a compact and efficient source of tunable radiation. Implementations using available nonlinear optical materials have been hampered because the gain and phasematching placed difficult constraints on the wavelength and power requirements of the pump laser [I]. With the engineerable phasematching and high gain ...
