LiF:F2- crystals have the advantages of high efficiency, convenience and stability when they are used for Q-switching of Nd glasslasers and the linewidth narrowing can be achieved in particular.
Q-switch erbium glasslasers have important application in eye-safe laser range finder. laser diode (LD) side-pumped erbium glass laser electro-optic Q-switch experiment is reported in this paper.
Over the last few years, glass fibers have gotten clearer, lasers are faster and cheaper, and processors have become many orders of magnitude more capable and available.
