Magneto-Optical Q-Switched Laser Generates Unpolarized Light

Facebook Twitter LinkedIn Email Comments
By using a technique — called q-switching — that utilizes short but high-powered pulse outputs, a laser one-tenth of the size of an American penny produced a beam that is 10 times more powerful than previously reported with larger lasers. The q-switch was performed in an Nd:YAG laser cavity. A research team from Toyohashi University of Technology fabricated the quasi-continuous-wave (QCW) diode-pumped Nd:YAG laser cavity, which was shortened to 10 mm in length and contained a RIG film and a pair of small coils. The first high-powered, randomly polarized laser...Read full article
