Phase stability of terawatt-class ultrabroadband parametric amplification.
The phase stability of broadband (280 nm bandwidth) terawatt-class parametric amplification was measured, for the first time to our knowledge, with a combination of spatial and spectral interferometry. Measurements at four different wavelengths from 750 to 900 nm were performed in combination with numerical modeling. The phase stability is better than 1/23 rms of an optical cycle for all the me...
متن کاملUltrabroadband noncollinear optical parametric amplification with LBO crystal.
Ultrabroadband visible noncollinear optical parametric amplification (NOPA) was achieved in an LBO crystal, with a continuum seed pulse generated from a sapphire plate. The spectral bandwidth of the amplified visible pulse was about 200 nm, which can support sub-5 fs pulse amplification. An amplified output of 0.21 microJ with an average gain of about 210 was achieved. This provides, to the bes...
متن کاملGeneration of few-cycle terawatt light pulses using optical parametric chirped pulse amplification.
We demonstrate the generation of 9.8+/-0.3 fs laser pulses with a peak power exceeding one terawatt at 30 Hz repetition rate, using optical parametric chirped pulse amplification. The amplifier is pumped by 140 mJ, 60 ps pulses at 532 nm, and amplifies seed pulses from a Ti:Sapphire oscillator to 23 mJ/pulse, resulting in 10.5 mJ/pulse after compression while amplified fluorescence is kept belo...
متن کاملHigh-repetition-rate near-infrared noncollinear ultrabroadband optical parametric amplification in KTiOPO4.
We report efficient noncollinear optical parametric amplification (NOPA) of ultrabroadband near-IR pulses tunable in the 1.1-1.5 μm range at a repetition rate of 250 kHz. Improved generation of smooth near-IR continua (extending over ~1.0-1.6 μm) at 250 kHz was achieved by weakly focusing ~20% of the 1 W driving laser beam into a sapphire plate with longer focal length lenses than previously re...
متن کاملContinuous - wave phase - sensitive parametric image amplification
(Received 00 Month 200x; In final form 00 Month 200x) We study experimentally parametric amplification in the continuous regime using a transverse-degenerate type-II Optical Parametric Oscillator operated below threshold. We demonstrate that this device is able to amplify either in the phase insensitive or phase sensitive way first a single mode beam, then a multimode image. Furthermore the tot...
