Tunable yellow–green laser based on second harmonic generation of LiF:F−2 in KTP
A yellow–green solid-state laser source based on frequency- doubling of a room temperature LiF:F−2 laser in KTP is reported. Second harmonic generation of free-running and prism-tuned pulsed lasers has been ch...

Improving the beam quality of solid-state systems using both outside and inside cavity devices with variable optical characteristics along the cross section
This paper presents the results of application to different laser installations of soft or apodized apertures (AA) [1–3] with smooth transmission profiles decreasing from center to edges. Two types of AA, whic...
