Abstract
Wavelength-stabilized compact laser systems at on a micro-optical bench are presented. The resonator concept consists of a tapered semiconductor gain medium and a reflection Bragg grating as a wavelength selective resonator mirror. In pulse operation mode with pulses, an optical peak power of with a spectral width below was achieved. Nearly diffraction-limited beam quality at optical output powers up to is obtained. Such laser systems can be used, e.g., for Raman spectroscopy and as pumping sources for frequency conversion toward UV spectral range.
