Laser oscillation method and laser device

摘要

To provide a laser oscillation method and a laser device, which use a laser medium such as an Nd:GdVO4 crystal to which neodymium is doped in high concentration exceeding 1% in atomicity ratio, the laser medium comprised of the gadolinium-vanadate crystal to which neodymium as laser active ion is doped by a floating zone method such that concentration becomes exceeding 1% in atomicity ratio.
