Abstract
The laser radiation apparatus is provided having substantial light emission intensity although the laser radiation apparatus is miniaturized. A solid state laser rod; the excitation light source formed such that the excitation light source surrounds an emission axis in a section perpendicular with respect to the emission axis of laser light of the solid state laser rod; and a lens barrel placed so that the lens barrel surrounds the excitation light source and condenses light from the excitation light source to the solid state laser rod. Excitation light reflected upon inner surface of the lens barrel is radiated uniformly over the lateral surface of the laser rod so that laser active medium is efficiently excited, and energy conversion rate is improved.
