Abstract

We present a femtosecond vertical external cavity surface emitting laser (VECSEL) that is continuously tunable in repetition rate from 6.5 GHz up to 11.3 GHz. The use of a low-saturation fluence semiconductor saturable absorber mirror (SESAM) enables stable cw modelocking with a simple cavity design, for which the laser mode area on SESAM and VECSEL are similar and do not significantly change for a variation in cavity length. Without any realignment of the cavity for the full tuning range, the pulse duration remained nearly constant around 625 fs with less than 3.5% standard deviation. The center wavelength only changed ±0.2 nm around 963.8 nm, while the output power was 169 mW with less than 6% standard deviation. Such a tunable repetition rate is interesting for various metrology applications such as optical sampling by laser cavity tuning (OSCAT).

a) Schematic overview of the V-shaped laser cavity, showing the pump geometry and the cavity elements: output coupler, QW-VECSEL and QD-SESAM. The repetition rate was changed by moving the output coupler in z-direction. TOC: output coupler transmission. ROC: radius of curvature of the output coupler. b) Simulated laser beam radii in the cavity (blue) for different cavity lengths and output coupler positions highlighted in red, also marked with the corresponding repetition rates. The two black lines indicate the positions of the QD-SESAM and the gain structure. The laser beam on the gain structure changes by less than +/−5% and is always smaller than the pump spot radius (120 µm).

Modelocking results obtained at a repetition rate of 10 GHz. a) Measured auto-correlation trace (blue) and fitted autocorrelation of a 607-fs sech2-pulse (red). b) Microwave spectrum with a resolution bandwidth of 100 kHz and a span of 10 MHz showing a repetition rate of 10 GHz. c) Measured optical spectrum with a spectral width of 2.04 nm around 963.7 nm in red with a spectral resolution of 0.1 nm (32 GHz) and in blue with a spectral resolution of 0.01 nm (3.2 GHz), where the longitudinal cavity modes can be partially resolved.

The repetition rate was tuned from 6.5 GHz up to 11.3 GHz. During the tuning we measured only small changes in output power (blue), with less than 6% standard deviation around 169 mW, while the pulse duration (red) was nearly constant around 625 fs with less than 3% standard deviation. The center wavelength (green) was extremely constant changing only about ±0.2 nm around 963.8 nm.
