▎ 摘　　要

NOVELTY - The laser has a pump source for providing a pump light and pumps by using a pulse pumping mode. A coupling system couples the pump light into a laser cavity. A gain medium generates a required 905 nm laser radiation. The gain medium is provided with a titanium-doped sapphire crystal. A Q-adjusting crystal generates the desired Q-switched pulse. The Q-adjusting crystal is provided with graphene or Chromium. The first cavity mirror and a second cavity mirror is formed between two laser resonant cavities and utilizes a 905 nm laser to form an oscillation output. USE - High repetition frequency integrated Q-adjusting microchip laser. ADVANTAGE - The laser utilizes for short service life of titanium-doped sapphire crystal level as the gain medium, and graphene with short recovering time as Q-adjusting crystal, adopts the pulse pumping mode to obtain stable and adjustable height of high repetition frequency and a short pulse width. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a high repetition frequency integrated q-adjusting microchip laser.
