TLDR
A diode-pumped chirped-pulse regenerative amplifier with a cooled Yb:YLF crystal with high effective extraction efficiency is developed, attributed to reduced saturation fluence at low temperature and to a high effective pulse energy fluence during regenerative amplification.Abstract:
A diode-pumped chirped-pulse regenerative amplifier with a cooled Yb:YLF crystal has been developed. The output pulse energy is 30 mJ at 20-Hz repetition rate. A high effective extraction efficiency of 68% is obtained, which is attributed to reduced saturation fluence at low temperature and to a high effective pulse energy fluence during regenerative amplification. After pulse compression by use of a parallel grating pair, 18-mJ pulse energy and 795-fs pulse duration are obtained.read more

The dynamics of small molecules in intense laser fields
TL;DR: In this paper, an experimentalist's point of view of the dynamics of H-2+ in an intense laser field is presented, which is interpreted in terms of bond-softening, vibrational trapping (bond-hardening), below-threshold dissociation and laser-induced alignment of the molecular axis.

TL;DR: It is demonstrated experimentally that an arbitrary phase and amplitude profile can be applied to an ultrashort pulse by use of an acousto-optic programmable dispersive filter (AOPDF) that has a large group-delay range and a 30% diffraction efficiency over 150 THz.
