Abstract
A laser beam axis monitoring apparatus which includes a laser oscillator generating a laser beam and a light generator for generating a light for monitoring an axis of the laser. The light from the light generator is split into ring-shaped light and reflected or lead into the laser oscillator. The light in the laser oscillator is reflected by a total reflection mirror and passes out of the oscillator so that the axis of the laser beam and axis of the light coincide with each other.
