Abstract: Transient signal measurements are bandwidth limited by present digitizer technology. If a transient signal can be stored in a gain-clamped regenerative delay line, such a signal can be regeneratively sampled, resulting in about an order of magnitude increase in measurement bandwidth. The approach involves converting electrical signals to optical signals with high fidelity, injecting such signals into a fiber-optic delay line, and then sampling injected signals repetitively, with signal generation provided by an erbium-doped gain-clamped fiber amplifier. Moreover, signal regeneration can be either steady state (i.e., amplification on each pass) or switched (i.e., amplification after signal levels have dropped significantly).

Abstract translation: 瞬态信号测量是由目前的数字化仪技术带宽限制的。 如果瞬态信号可以存储在增益钳位的再生延迟线中，则可以对这样的信号进行再生采样，从而导致测量带宽增加大约一个数量级。 该方法涉及将电信号转换为具有高保真度的光信号，将这些信号注入到光纤延迟线中，然后用掺铒增益钳位光纤放大器提供的信号产生重复采样注入的信号。 此外，信号再生可以是稳定状态（即，每次通过时的放大）或切换（即，在信号电平显着下降之后的放大）。

Abstract: The system has a single pulse spectrum capability for sensing the presence of contamination on a surface to be interrogated. The system includes a narrow frequency bandwidth visible pulse and broadband infrared pulse that are directed to the surface. An output wavelength discriminator receives the reflected sum-frequency that is generated. The output wavelength discriminator is substantially non-transmissive at the frequencies of the visible pulse and the infrared pulse, but is substantially transmissive at the sum-frequency of the visible pulse and the infrared pulse. The output of the wavelength discriminator is a broadband output. A frequency disperser receives the output of the wavelength discriminator and provides a physical separation of output wavelengths of the broadband output. A multi-channel analyzer analyzes the intensity of the physically separated output wavelengths as a function of their physical positions. Thus, a wavelength dependent intensity measurement is provided that is indicative of the presence of contamination.

Abstract: A pulse laser which outputs a pulsed laser beam, comprises a delaying means which delays the timing of shift from off to on of a laser output timing signal which is turned on during the output period of the pulse laser for the time required to output one laser pulse and an average output measuring means which measures the average output of the pulse laser while the laser output timing signal is on. The average output of the pulse laser is accurately measured by eliminating the influence of giant pulses.

Abstract: A dielectric dispersion determining method applying a transient grating method. The transient response of a sample is observed by the transient grating method using a femtosecond ultrashort visible optical pulse. A vibrational waveform b(t) is determined such that its square b(t).sup.2 replicates vibrational components observed in the transient response. The vibrational waveform b(t) is converted into b(.omega.) through the Fourier transform. The dielectric constant .epsilon.(.omega.) is obtained by substituting the converted value for b(.omega.)/.omega..sup.2 on the right-hand side of the following equation (1) derived from Maxwell's equations. The dielectric constant and/or refraction index can be directly obtained from the transient response to the femtosecond ultrashort visible optical pulse without passing through the dispersion relation which leaves some ambiguity in its definition. ##EQU1##
