摘要

A new scheme of a highly-reliable glass-based color wheel applied to a laser light engine (LLE) for a high-power laser operation is demonstrated for the first time. The glassbased color wheel showed better thermal stability than the silicone-based color wheel, about 13.6 times less lumen loss and 3 times less chromaticity shift after being operated under a 30 Wopt laser for 2000 hours, respectively. The excellent thermal stability can be attributed to the high glass transition temperature up to 570 °C exhibited by the glass-based color wheel. The easy fabrication and the good reliability on optical performance under thermal stress benefit the novel glass-based color wheels as promising candidates to replace the siliconebased color wheels in the LLE modules for the next-generation laser projector.
