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, 3x105 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.

Ultra-broad bandwidth parametric amplification at degeneracy

J. Limpert, C. Aguergaray, S. Montant, I. Manek-Honninger, S. Petit, D. Descamps, E. Cormier, F. 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.
