Laser-written waveguides in KTP for broadband Type II second harmonic generation
- 2012

Tidskriftsartikel (refereegranskat)abstract
- Femto-second laser writing was used to fabricate waveguides in a z-cut KTP sample with losses below 0.8 dB/ cm. They were used for efficient, broad bandwidth, Type II birefringent second harmonic generation to the green. The temperature and wavelength bandwidth were, 28 degrees C.cm and 0.85 nm.cm, respectively.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Highly reflecting volume Bragg gratings (VBGs) written in photo-thermo-refractive glass [1], have been successfully employed for spectral control of solid-state lasers [2, 3]. This presentation will review the recent progress in the field.

Accurate modeling of high-repetition rate ultrashort pulse amplification in optical fibers
- 2016
-
Ingår i: Scientific Reports. - : Nature Publishing Group. - 2045-2322. ; 6
-
Tidskriftsartikel (refereegranskat)abstract
- A numerical model for amplification of ultrashort pulses with high repetition rates in fiber amplifiers is presented. The pulse propagation is modeled by jointly solving the steady-state rate equations and the generalized nonlinear Schrödinger equation, which allows accurate treatment of nonlinear and dispersive effects whilst considering arbitrary spatial and spectral gain dependencies. Comparison of data acquired by using the developed model and experimental results prove to be in good agreement.
