Abstract

A high power, two color, collinear, blue and green vertical external cavity surface emitting laser (VECSEL) is demonstrated. Two different InGaAs/GaAs VECSEL chips operating with gain centers near 970 nm and 1070 nm are used to make two separate V-folded laser cavities. Two critically phase-matched intracavity lithium triborate nonlinear crystals are used to generate blue and green outputs which are then combined in a polarizing beam splitter. This results in a single beam which contains over 10 watts of combined blue and green output power. This concept can be expanded upon by adding a red output for the creation of a high power, white laser source.
