Abstract

We investigate the impact of the spectral detuning between micro-cavity resonance and material gain on the high-power operation of semiconductor disk lasers exploiting the connection between cavity angle and micro-cavity resonance. Our investigation shows that by altering the cavity-angle-dependent detuning, we can modify such device’s performance in strong correlation with the detuning. A change of the maximum output power by factor of two is observed. The threshold pump powers are even modified by a factor of four. Moreover, the wavelength tunability is investigated, showing that it can be enhanced by the choice of a respective detuning.
