    Abstract: Provided is a single pulse laser apparatus. The apparatus including a resonator having a first mirror, a second mirror, a gain medium, and electro-optic modulators (EOMs) which perform each mode-locking and Q-switching, the apparatus includes a photodiode which measures laser light that oscillates from the resonator, a synchronizer which converts an electrical signal generated by measuring the laser light into a transistor-transistor logic (TTL) signal, a delay unit which sets a latency determined in order to synchronize a mode-locked pulse with a Q-switched pulse to the TTL signal, and outputs a trigger TTL signal according to the latency, and a Q-driver which inputs the trigger TTL signal to the EOM which performs Q-switching, and causes the EOM to operates.

    Abstract: Disclosed are herein an apparatus and method for extreme ultraviolet (EUV) spectroscope calibration. The apparatus for EUV spectroscope calibration includes an EUV generating module, an Al filter, a diffraction grating, a CCD camera, a spectrum conversion module, and a control module that compares a wavelength value corresponding to a maximum peak among peaks of the spectrum depending on the order of the EUV light converted from the spectrum conversion module with a predetermined reference wavelength value depending on an order of high-order harmonics to calculate a difference value with the closest reference wavelength value, and controls the spectrum depending on the order of the EUV light converted from the spectrum conversion module to be moved in a direction of wavelength axis by the calculated difference value. Thus, it is possible to accurately measure a wavelength of a spectrum of EUV light used in EUV exposure technology and mask inspection technology.

    Abstract: A plasmonic all-optical switch includes a graphene layer, a first dielectric layer located on the graphene layer, a nano-antenna located on the first dielectric layer, and a second dielectric layer located on the nano-antenna. An incident beam is propagated by means of a surface plasmon wave generated at an interface between the graphene layer and the first dielectric layer. Further, localized surface plasmon resonance is selectively generated at an interface between the nano-antenna and the second dielectric layer by means of a pump beam incident to the nano-antenna to decrease an intensity of the incident beam. The plasmonic all-optical switch may operate at an ultrahigh speed just with a small light energy without any electric method, greatly reduce power consumption of an IT device by applying to an all-optical transistor or the like, and increase a processing rate.
