Parasitic lasing suppression in high gain femtosecond petawatt Ti:sapphire amplifier.
نویسندگان
چکیده
New parasitic lasing suppression techniques are developed and high gain amplification is demonstrated in a petawatt level Ti:sapphire amplifier based on the chirped pulse amplification (CPA) scheme. Cladding the large aperture Ti:sapphire with refractive-index matched liquid doped with absorber suppresses the transverse lasing. The acousto-optic programmable dispersive filter (AOPDF) is used to realize side-lobe suppression in the temporal profile of the compressed pulse. The 800 nm laser output with peak power of 0.89 PW and pulse width of 29.0 fs is demonstrated.

A compact 355TW femtosecod Ti:sapphire laser facility and trend to high contrast ratio
A Ti:sapphire laser facility is established based on the chirped pulse amplification technology. For the first time we generate laser peak power of multi-100TW with three stages of amplifiers. In the final amplifier a 100J frequency-doubled Nd:glass laser is used as the pump source. To suppress the parasitic lasing (PL), we design the Ti:sapphire crystal with V groove cutting shape and use poly...

An ultrafast laser system for the chemically important 3-mm spectral region has been constructed by means of noncritically phased-matched KTiOPO4 optical parametric gain elements. An optical parametric oscillator, synchronously pumped by a mode-locked Ti:sapphire oscillator, generates high-quality seed pulses for an optical parametric amplifier. The optical parametric amplifier, pumped by a hig...

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 ...
متن کاملHigh 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...

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...
