For example, such a light source may be a laser. ), And the light source generator may be a laser light source generator that converts an electrical signal into a laser.

Since the laser is light having the same wavelength, phase, and propagation direction, the intensity is very strong and does not spread far, the laser light source generator generates light source energy while minimizing energy loss to spaced-apart energy receivers. Can be easily delivered.

In one preferred embodiment, the laser light source generator is configured to include a power input, a laser diode pump source, a laser crystal, a spectrometer, and an output articulator, and converts electrical energy input to the power input into light energy and outputs the light. The occlusal system can be used to investigate outside.

Specifically, in the laser light source generator, the power input unit receives power from the outside, and the laser diode pump source generates the laser light source using the supplied power. The laser light source generated from the diode pump source is converted into a laser light source having a specific wavelength region through the laser crystal, and the linearity of the laser light source is improved while passing through the spectrometer. The plurality of laser light sources are collected into a single constant laser light source through the output bite, and the collected single constant laser light sources are irradiated to the outside.
