International Classification:

H01S 3/115

US Classification:

Abstract:

A high-power diode end-pumped solid-state UV laser comprises high-power fiber-coupled end pumping laser diodes, a specially designed fundamental laser cavity and multiple high-power high-efficiency harmonic generations. Nonuniform fundamental laser cavity has to be used, i.e. the beam size of the fundamental laser cannot be uniform in the fundamental cavity. Thermal transfer inside the laser crystal and harmonic crystal has to be specially and carefully treated, and special crystal mounts were designed to optimize the thermal contact and maximize the heat transfer. In addition, harmonic crystal mounts were specially designed to minimize the loss and protect the hydroscopic crystals.

Abstract:

In this invention, multiple pairs of reflective mirror on a high-precision stable rotation stage generate a repetitive wide range delay in a noncolinear intensity autocorrelator. Such autocorrelator is real-time, background-free, dispersion free. It has a continuous long scanning range, from a few femtoseconds to hundreds of picoseconds.
