Abstract

We demonstrate the highest free running single frequency power from a single chip VECSEL reported to date, with more than 15W in continuous operation at room temperature. The GaAs-based structure presents an emission wavelength of 1020nm and a tuning range <15nm, with a continuous tunability of 9GHz. The TEM00 output beam exhibits very low transverse phase fluctuations across the entire mode, leading to a beam quality M2 <1.2. To identify and reduce the different sources of noise, the relative intensity noise and frequency noise spectral density are investigated and the intensity and the frequency of the laser were independently stabilized. The laser frequency is controlled and tuned varying the cavity length using a high bandwidth piezoelectric element while intensity fluctuations are reduced by varying the pump intensity. Intrinsic and stabilized frequency and intensity noise are compared.
