Base-induced cycloadditions of tosylmethyl isocyanide to a series of isothiocyanates have been investigated. Depending on the reaction conditions, thiazoles 5 and/or imidazoles 7 are obtained, with the thiazoles, in particular, being obtained with hi

We report the implementation and operation of novel superhigh-reflectivity negative-dispersion dielectric mirrors for use in tunable ultrafast laser systems. The mirror structure is divided into two distinct regions: an underlying superhigh-reflectiv

Propagation of intense femtosecond pulses in solids and liquids is investigated experimentally and numerically. A brief review of experiments in fused silica that reveal complicated spatio-temporal dynamics including temporal pulse splitting is prese

Summary form only given. Because of the broad bandwidth of femtosecond laser pulses, dispersion coefficients are important parameters in femtosecond pulse propagation. Dispersion coefficients of dielectrics and nonlinear materials such as barium bora

Amorphous alloys of the type A1−xFex, where A represents B, Ge, or Sn, were prepared by two‐source coevaporation in the ranges 0.3⩽x⩽0.9, 0.30⩽x⩽0.65, and 0.45⩽x⩽0.64. The magneto‐optical properties of these alloys were examined by

TE‐TM mode conversion was studied in LPE‐grown garnet films with high Faraday rotation (up to 1800 °/cm at 1.15‐μm wavelength) and positive uniaxial anisotropy. High conversion ratios (80–90%) were found for several modes. The phase matchin
