Linearly Polarized Dual-Wavelength Vertical-External-Cavity Surface- Emitting Laser (Postprint); Journal article

摘要

The authors demonstrate the multiwatt linearly polarized dual- wavelength operation in an optically pumped vertical-external-cavity surface- emitting laser by means of an intracavity tilted Fabry-Perot etalon and a Brewster window. The sum frequency generation from the lithium triborate crystal pumped by this laser confirms that these two wavelengths oscillate simultaneously. Over 30 dB side-mode suppression can be achieved at dual wavelengths with a spectral spacing of 2.1 nm. The output power is slightly reduced by the intracavity Fabry-Perot etalon and Brewster window.
