TLDR
This source was used to produce 1 W of femtosecond white light through spectral continuum generation and was amplified at repetition rates of as much as 7.2 kHz in a Ti:Al(2)O(3) regenerative amplifier pumped by a frequency-doubled Q-switched Nd:YLF laser.
Abstract
We amplified femtosecond pulses at repetition rates of as much as 7.2 kHz in a Ti:Al2O3 regenerative amplifier pumped by a frequency-doubled Q-switched Nd:YLF laser. Energies of as much as 1 mJ at 1 kHz and 85 μJ at 7.2 kHz in a 150-fs pulse have been obtained. This source was used to produce 1 W of femtosecond white light through spectral continuum generation.

All-Optical Histology Using Ultrashort Laser Pulses

TL;DR: It is shown that the permeability, immunoreactivity, and optical clarity of the tissue is retained after pulsed laser cutting, and samples from transgenic mice that express fluorescent proteins retained their fluorescence to within microns of the cut surface.

Mode locking of Ti:Al 2 O 3 lasers and self-focusing: a Gaussian approximation

TL;DR: An ABCD matrix model is presented showing that self-focusing in the laser rod leads to modifications of the Gaussian beam parameters in cw-pumped Ti:Al(2)O(3) lasers, and stabilization of self-mode-locking should result from these beam perturbations.
