摘      要：We evaluate and demonstrate ultra-broadband near-infrared noncollinear optical parametric amplification in two nonlinear crystals,bismuth borate(Bi BO)and yttrium calcium oxyborate(YCOB),which are not commonly used for this *** spectral bandwidth is of the microjoule level;the amplified signal is≥200 nm,capable of supporting sub-10 fs *** results,supported by numerical simulations,show that these crystals have a great potential as nonlinear media in both low-energy,few-cycle systems and high peak power amplifiers for terawatt to petawatt systems based on noncollinear optical parametric chirped pulse amplification(NOPCPA)or a hybrid.
