Laser system used as laser wavelength conversion system comprises non-linear optical crystal for harmonically producing laser light base wave irradiated from laser light source, and sealed cell having chamber and window
A laser system comprises a non-linear optical crystal (43) for harmonically producing a laser light base wave irradiated from a laser light source, and a sealed cell (40) having a chamber (42) for the path of the laser light and a window for covering the chamber. The crystal is arranged in the cell and the inner surface is treated so that it repels water.
