Very compact and high-power CW self-Raman laser for ophthalmological applications

Abstract: In this work, we present a continuous-wave yellow laser operating at 586.5nm based on self-Raman conversion in Nd:GdVO 4 . We report more than 4.2W CW and 5.5W instantaneous output at a 50% duty cycle regime. This is the highest CW power of a self-Raman laser to be reported so far. We also demonstrate the integration of this laser cavity into a console for applications in ophthalmology, and more specifically for retinal photocoagulation therapies.

“…Short laser exposure duration avoids photoreceptor lesions on the retina, providing a better final vision [1]. The laser cavity in 586nm and 4W CW output power is based on Self-Raman conversion in Nd:GdVO4 [2], [3]. Initially, it was developed to continuous mode, but now it is switched to 500Hz, with minimum pulse duration of up to 100µs.…”
