Picosecond Pulse-Pumped Efficient Optical Parametric Amplifier for Non-Chirped Femtosecond Pulses Hua Yang Notes: 1.Simulations performed with 10 fs and 50 fs signal at 1054 nm with 1 nJ energy input. 2.Amplification of chirped pulse has no advantage over non-chirped pulse in swept OPA scheme. 3.No experimental results were obtained.

Ultra-broadband chirped-pulse optical parametric amplifier with angularly dispersed beams Gunnar Arisholm Notes: 1.Uses tilted pulse front of signal to realize group velocity matching. 2.Pumping at 400 nm with 1.7 mJ of energy and a 3.8-fs seed pulse, 3x10 5 gain was achieved in 2.8-mm BBO. 3.No experimental results were obtained.

Second-harmonic generation of weak femtosecond pulses under the condition of vanishing group-velocity mismatch Wanguo Zheng, Wei Han, Liejia Qian, Peng Yuan, Guoqiang Xie, Hang Luo, Heyuan Zhu and Dianyuan Fan Notes: 1.In the case of low GVM, GVD has a strong effect on conversion efficiency. 2.Case of zero GVM necessitates the need for longer crystal for increased conversion efficiency because of GVD. 3.Conversion efficiency is maximized at FTL position for pre-chirped pump.

Salin Notes: 1.Performed around degeneracy (400 nm pump, 800 nm signal). 2.Cubic phase required for signal with linear chirp of pump to ensure temporal overlap of phase-matched spectral components. 3.Largest reported bandwidth for parametric amplification at degeneracy by tuning angular dispersion of pump.
