Laser irradiation light detecting device |
摘要 |
The present invention relates particularly to a laser irradiation light detecting device having detecting means for receiving a reflected light pencil of a laser light pencil applied from a laser irradiating device provided with a non-linear optical medium for generating a second harmonic. A laser light source pumps an optical resonator and a pulse driving means drives the laser light source. An irradiating means applies a pencil of pulse laser light produced from a laser oscillating device to a target device. A detecting means detects a light pencil reflected from the target device. An arithmetic processing means executes predetermined operations, based on the signal detected by the detecting means. The detecting means detects the reflected light pencil of the pulse laser light pencil in synchronism with a period T of a driving pulse of the pulse driving means.
