IPC: G02F1/35
Filed: 1984-03-12
Abstract: PURPOSE:To enable to measure only the reflected light from a nonlinear optical crystal, by providing a gate means, which passes a signal which is related only with the first reflected light, among the first reflected light from the nonlineary type crystal and the second reflected light from plasma. CONSTITUTION:A laser-energy measuring device is provided with the following parts: a gate pulse generator 12; an integrating type A/D converter 13 with a gate, which is operated by gate pulses; and a processing and displaying device 14, which displays the measured value. The gate pulse generator 12 generates a signal 18 at the time when a signal 16 is generated by the reflected light from a nonlinear crystal 5. The signal 18 is applied to the integrating type A/D converter 13 with the gate. Only the energy of the signal 16 is measured. The measured value is converted by the processing and displaying device 14 and the result is displayed. Thus only the reflected light from the nonlinear optical crystal can be measured.
