Abstract:
    An ultrashort pulse frequency distinguishing optics switch measuring equipment, including: only one 1*2 reflecting Dammann grating, the first reflector, the second reflector, the third reflector, the jiggling desk, the lens, the non-linear crystal and the wavelength spectrometer, the invention is that only uses one reflecting Dammann grating and three reflectors to achieve the measurement of the ultrashort pulsed light, thereby avoids the effect from the traditional transmissive / reflecting spectroscope to the pulsed light, the producing technology of Dammann grating is compatible with the processing technology of microelectronics.
