Ultrabroadband 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 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 کاملDesign considerations for a high power, ultrabroadband optical parametric chirped-pulse amplifier.
A conceptual design of a high power, ultrabroadband optical parametric chirped-pulse amplifier (OPCPA) was carried out comparing nonlinear crystals (LBO and BBO) for 810 nm centered, sub-7.0 fs pulses with energies above 1 mJ. These amplifiers are only possible with a parallel development of kilowatt-level OPCPA-pump amplifiers. It is therefore important to know good strategies to use the avail...
متن کاملPhase 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 کاملThermal properties of borate crystals for high power optical parametric chirped-pulse amplification.
The potential of borate crystals, BBO, LBO and BiBO, for high average power scaling of optical parametric chirped-pulse amplifiers is investigated. Up-to-date measurements of the absorption coefficients at 515 nm and the thermal conductivities are presented. The measured absorption coefficients are a factor of 10-100 lower than reported by the literature for BBO and LBO. For BBO, a large variat...
