Properties of Volume Bragg Gratings and Nonlinear Crystals for Laser Engineering

Autor: Tjörnhammar, Staffan

This thesis focuses on two topics: thermal limitations of volume Bragg gratings (VBGs) employed as laser-cavity mirrors and formation of color centers in KTiOPO4 and its isomorphs. To explore the mechanisms of the thermal limitations of VBGs in high

Pulsed Yb:KYW laser and UV generation

Autor: Tjörnhammar, Staffan

In this master thesis project, a pulsed UV laser was designed and constructed. Also, the effects of absorption in a volume Bragg grating were investigated. The laser was diode pumped and constructed with Yb:KYW as gain medium. The lasing was at a wav

Thermal limitations of volume Bragg gratings when used in lasers for spectral control

Autor: Tjörnhammar, Staffan, Jacobsson, Björn, Pasiskevicius, Valdas, Laurell, Fredrik

We investigated the effect of absorption in volume Bragg gratings (VBGs) and the associated temperature effects that appear when they are used as mirrors in diode pumped solid-state lasers. The primary result is an uneven longitudinal temperature dis
