چکیده

We experimentally demonstrated the contrast enhancement in a Ti:sapphire chirped-pulse amplification (CPA) laser with a noncollinear femtosecond optical-parametric amplifier. A total gain of 3.4 × 10(4) and pulse energy of 26 μJ were achieved. With the clean high-energy seeding pulse, the contrast ratio of the main amplified laser pulse to the amplified spontaneous emission in the Ti: sapphire CPA laser system was improved to around 10(10) within the time scale of hundreds of picoseconds.

Nonlinear temporal pulse cleaning techniques and application

Two different pulse cleaning techniques for ultra-high contrast laser systems are comparably analysed in this work. The first pulse cleaning technique is based on noncollinear femtosecond optical-parametric amplification (NOPA) and second-harmonic generation (SHG) processes. The other is based on cross-polarized wave (XPW) generation. With a double chirped pulse amplifier (double-CPA) scheme, a...

High-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...

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...

A source of 2 terawatt, 2.7 cycle laser pulses based on noncollinear optical parametric chirped pulse amplification.

We demonstrate a noncollinear optical parametric chirped pulse amplifier system that produces 7.6 fs pulses with a peak power of 2 terawatt at 30 Hz repetition rate. Using an ultra-broadband Ti:Sapphire seed oscillator and grating-based stretching and compression combined with an LCD phase-shaper, we amplify a 310 nm wide spectrum with a total gain of 3x10(7), and compress it within 5% of its F...

Development of cryogenically-cooled Yb:YLF chirped-pulse amplification laser for pumping few-cycle optical-parametric chirped-pulse amplification

As a pump source for intense few-cycle laser system with optical-parametric chirped-pulse amplification (OPCPA), we have been developing cryogenically-cooled Yb:YLF chirped-pulse amplification laser. So far we have successfully obtained high energy output pulse with 107 mJ of energy from a single-stage regenerative amplifier, which can be compressed to 2.2 ps in duration without pedestal.
