The use of glasses doped with PbS nanocrystals as intracavity saturable absorbers for passive Q-switching and mode locking of c-cut Nd:Gd0.7Y0.3VO4, Nd:YVO4, and Nd:GdVO4 lasers is investigated. Q-switching yields pulses as short as 35 ns with an ave

Optical Fibers With a Finite Metallic Core

Autor: Reto Bloch, Willy Lüthy, Thomas Feurer

Publikováno v: Journal of Lightwave Technology. 27:1454-1460

Optical step index fibers can be produced that include a thin metal wire in the centre of the core. Such fibers are particularly interesting with respect to their guiding properties. With the goal to theoretically analyse their modes, we summarize th

In this paper we report the fabrication of graphitic microstructures in the bulk of diamond using 120-fs-laser pulses at 800 nm wavelength. Polished plates of single crystal diamond and optical quality polycrystalline CVD diamond were used as samples

A Nd:Gd0.7Y0.3VO4 crystal is grown in laser quality. The crystal is diode-pumped at 808 nm. When operated in a Z-shaped resonator with an acousto-optical modulator in combination with a Kerr lens, it produces pulses of 1.7 ps at 140 MHz repetition ra

A novel technique for active fibre production

Autor: R Renner-Erny, Loredana Di Labio, Willy Lüthy

Publikováno v: Optical Materials. 29:919-922

Active fibre devices are conventionally manufactured using MCVD technique. Recently it has been shown that nearly equivalent results can also be obtained with sol–gel technology. Now we present a novel technique allowing simplification of the manuf
