Paper Abstract

We present a serially-connected two-chip vertical-external-cavity surface-emitting laser design, which generates dual wavelength emission with a wavelength separation of 10 nm and over 600 W intracavity power. Intracavity type-I second-harmonic generation and sum-frequency generation have been performed in a LiNbO3 crystal. By employing different chip-combinations as well as birefringent filters, the laser is able to generate high-power emission with two wavelengths, which exhibit the same polarization and a desirable wavelength separation. Furthermore, the dependence of the emission wavelength on the cavity angle on the VECSEL chip is highlighted, which provides an additional means of wavelength tuning in VECSELs.
