Abstract
A laser irradiation system includes a laser diode as a laser generation source, a lens for receiving the laser light introduced thereto from the laser diode and producing a laser beam, and a light pipe for receiving the laser beam produced by the lens and introduced thereto, wherein the light pipe has a hollow portion for guiding the introduced laser beam for irradiation therewith, and an outer tube portion for emitting light by scattering the introduced laser beam, whereby the irradiation with laser being conducted can be clearly indicated so that the user can easily notice the situation even in the cases of unintended irradiation with laser.
