摘要： System(s) and method(s) to probe electromagnetic fields at the surface of a solid-state material are provided. The technique combines ultrafast (e.g., less than 10 fs) optical excitation and electron microscopy to generate electronic excitations and image the ensuing electromagnetic fields with nanometer-scale spatial resolution and femtosecond time-scale resolution. In addition, time-of-flight energy analysis facilitates imaging of relaxation a generated electronic excitation. The dynamics of the electromagnetic fields can be probed interferometrically through generation of multi-frame imaging, with inter-frame frequency of the order of a few hundreds of attoseconds, of interference patterns among an electric field associated with an excitation in a sample or device and the electromagnetic field of a probe pulse coherent with an excitation pulse. Quality assurance of nanoscopic devices based on plasmonic, photonic, electronic, spintronic operation can be analyzed with spectroscopy provided in the subject innovation.

摘要： An optical signal synthesizer having an optical slab waveguide constructed from three layers in which optical pulses are introduced. A first cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens which collimates the introduced optical pulses, a second cut-away portion of the optical slab waveguide serving as a diffraction grating for parallel light beams in which the optical pulses are separated into every frequency, and a third cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens by which the separated optical pulses are focused on a different spatial position associated with each frequency. A spatial light modulator is fabricated at the focusing position in the optical slab waveguide which allows the optical pulses subjected to optical modulation every frequency to pass therethrough according to an applied electrical signal. A fourth cut-away portion of the optical slab waveguide has a plano-concave shape serving as a plano-convex lens which collimates each modulated optical frequency component individually, and a fifth cut-away portion of the optical slab waveguide serving as a diffraction grating for the modulated optical pulses restores the modulated optical pulses to the parallel light beams.

摘要： A compact solid-state laser has its cavity formed by the reflection surface of a gain crystal and the reflection surface of a chirped mirror. Pumping light is incident to the cavity through the reflection surface of the gain crystal or the chirped mirror, from which the laser output is led out. Forming of the cavity solely by the gain crystal and chirped mirror enables the elimination of additional component parts for the compensation of dispersion, thereby making the entire laser system compact, and consequently permitting an increase in the repetition frequency.

摘要： In a solid-state laser in which a gain crystal is polished to have the Brewster angle or a solid-state laser comprising a dichroic concave mirror to which light enters at an incidence angle which is not zero, astigmatism generally occurs in pumping light. By tilting a focusing lens for pumping light with respect to the optical axis of the pumping light, the astigmatism is compensated. The tilting angle is determined in such a manner that synthetic focusing points in the sagittal and tangential planes, of a series optical system of a focusing lens, a dichroic concave lens, and a gain crystal are calculated and the focusing points almost coincide with focusing points in a cavity mode.

摘要： A solid-state laser having an excitation light source, a lens system for focusing an excitation light produced from the light source, and a laser resonator which is laser-oscillated in response to the focused excitation light. The resonator includes only a gain medium and a solid-state medium having dispersion of a wavelength dependence opposite to that of the gain medium, and surfaces of the gain medium and the solid-state medium, which are respectively at opposite sides of opposing surfaces of the gain medium and the solid-state medium, are reflectively coated and act as mirror surfaces. At least one of the other surfaces of the gain medium and the solid-state medium, which ate positioned inside the resonator and are opposite to each other, is polished to a curved surface. The gain medium is excited by the focused excitation light so that the laser oscillation is made in the resonator.

摘要： A femtosecond pulse incident on a Mach-Zehnder interferometer is divided into two optical paths and thereafter synthesized again. The synthesized optical pulse is outputted as complementary two output optical pulses corresponding to the difference between optical paths. An optical interferometer for monitoring fluctuations of the optical path difference from one of two output optical pulses produced from an interferometer, effecting feedback on the optical path difference and providing an operation stabilized in a relation of 1/20 or less the central wavelength, and an optical signal synthesizer using the interferometer are provided.

摘要： In the wavelength-division-multiplexed optical transmission, laser diodes of the number of multiplicity are disposed as a light source to configure a transmitter. However, since this method requires a large number of light sources and highly precise wavelength control, a cost and an apparatus are increased. An ultrashort pulse solid-state laser is used as the light source of the transmitter and its wide spectrum is taken out by a splitter to be assigned to each channel, so that the number of light sources can be reduced greatly. The transmitter requires high repetition rate such as 2.4 GHz, 10 HGz and the like as the repetition rate of the ultrashort pulse solid-state laser, while by configuring the resonator only by two components as shown in FIG. 1, the high repetition rate can be attained. Since each channel is produced passively from the splitter, very precise wavelength management is not required. The light source is made small and the number thereof is reduced. Consequently, the whole apparatus is made small and a cost thereof is also reduced.
摘要翻译：在波分复用光传输中，将多个数量的激光二极管设置为光源以配置发射机。然而，由于该方法需要大量的光源和高精度的波长控制，所以成本和装置都增加。使用超短脉冲固态激光器作为发射器的光源，并且其分配器将其宽谱线分配给每个通道，从而可以大大减少光源的数量。发射机需要高重复频率，例如2.4GHz，10Hz等等作为超短脉冲固态激光器的重复频率，而通过仅由两个部件构成谐振器，如图3所示。如图1所示，可以实现高重复率。由于每个通道都是从分离器被动产生的，所以不需要非常精确的波长管理。光源变小，数量减少。因此，整个装置变小，成本也降低。
