Using a two stage, white-light seeded, collinear, femtosecond optical parametric amplifier based on BIBO crystal, sub-30-fs signal pulses with energies exceeding 200-muJ, corresponding to 5-fold pulse shortening and ~30% internal conversion efficiency, are generated.
The nonlinear refractive index of the monoclinic biaxial nonlinear crystal BiB3O6 was measured at 1064 nm and strong anisotropy was observed with about two times larger value for E//Z-axis in comparison to E//X-axis.
Ultrabroadband generation of white-light continuum in the near-IR (~135 THz, 1.15-2.4 mum) is demonstrated in BiB3O6, pumped by 45 fs long pulses at 800 nm, achieving an energy of 15 muJ at 1 kHz.
Here we report on ultrabroadband optical parametric amplification (OPA) in the relatively new nonlinear crystal bismuth triborate, BiB306 (BIBO), pumped by the fundamental of a 1 kHz Ti:sapphire laser system (lambdap=800 nm).
