Abstract:
An autocorrelation measurement device includes a first reflection member, a second reflection member, a focusing unit, a nonlinear optical crystal, a detection unit, a filter, an aperture, a delay adjusting unit, and an analysis unit. Incident pulsed light is transmitted through the second reflection member and incident on the first reflection member. First pulsed light reflected on a first reflection surface of the first reflection member and a second reflection surface of the second reflection member and second pulsed light reflected on a second reflection surface of the first reflection member and a first reflection surface of the second reflection member are incident on the nonlinear optical crystal via the focusing unit. Second harmonic light generated in the nonlinear optical crystal is detected by the detection unit.

Claim (Index 1):
An autocorrelation measurement device comprising:\n a first reflection member having a first reflection surface for reflecting a part of incident pulsed light and a second reflection surface for reflecting light transmitted through the first reflection surface in the incident pulsed light; a second reflection member having a first reflection surface for reflecting a part of light emitted from the first reflection member and a second reflection surface for reflecting light transmitted through the first reflection surface in the light; a focusing unit configured to focus first pulsed light reflected on the first reflection surface of the first reflection member and the second reflection surface of the second reflection member and second pulsed light reflected on the second reflection surface of the first reflection member and the first reflection surface of the second reflection member; a nonlinear optical crystal disposed on a focusing position by the focusing unit and configured to generate second harmonic light by incidence of the first pulsed light and the second pulsed light; a detection unit configured to detect the second harmonic light; a delay adjusting unit configured to change a delay time between the first pulsed light and the second pulsed light incident on the nonlinear optical crystal; and an analysis unit configured to obtain a pulse width of the incident pulsed light on the basis of a relationship between the delay time set by the delay adjusting unit and a detection result by the detection unit.
