We explore the potential of a new laser resonator design that uses an intracavity Fourier transformation and allows for multi-color operation, gain extension and intracavity second harmonic generation (SHG). First, purely electronically controlled wavelength tuning is demonstrated using liquid crystal displays (LCDs) and digital mirror devices. Moreover, the new design can be applied to different...
The transverse mode dynamics of vertical-cavity surface-emitting lasers is analyzed studying the passive cavity beam shaping mechanisms. Diffraction in the Bragg mirrors is found to favor the fundamental transverse mode compared to the higher order modes. Mode dependent effective complex reflection coefficients are computed. The effect of diffraction is compared to the effects of thermal lensing due...
