PURPOSE: To increase the output and oscillating efficiency by widely distributing the laser beams centered on the optical axis of laser mediums in relation to the laser oscillator.
CONSTITUTION: The laser oscillator is composed of an exciting light source 1 substantially in point or linear light source state, a reflecting cylinder 2 having cylindrical reflecting surface 2a wherein exciting light enters from the exciting light sourse 1 and rod type laser mediums 3 arranged to be centered on the optical axis of the reflecting cylinder 2. Within the laser oscillator, the excited light from the exciting light source 1 in the point and linear light source state is reflected on the cylindrical reflecting surface 2a to be condensed on the center for turning it into the imaginative point light source further to be condensed on the rod type laser mediums 3 for focussing step so that the laser beams may be excited to reflect the excited light passing through the laser mediums 3 for repeatedly focussing the same.
