We have evaluated barium metaborate ( β-BaB2O4) for its use in the measurement of ultrashort optical pulses. Using crystals grown in our laboratory, we have found that pulses as short as 50 fs can be measured accurately with a crystal 1.8 mm thick. The advantages of using barium metaborate rather than potassium dihydrogen phosphate (KDP) or ammonium dihydrogen phosphate (ADP) for autocorrelation measurements are discussed.

    Surface transformations in crystalline silicon are investigated, using 400 fs laser pulses, at intensities just above the melting threshold. Anomalous changes of surface heights are observed, and they are enhanced for shorter pulses. These experimental results are well understood with a picture...

    A model is proposed for the ignition of a defect-density switching wave in a crystal by powerful laser pulses. It is shown that the switching wave arises as a result of the nonlinear dependence of the activation energy of the defect-formation process on the strain field due to defects. The...

    Abstract. We report on the diffraction of ultrashort laser pulses by single and double slits. The first-order diffraction was investigated as a function of the spectral bandwidth and the temporal duration of the laser pulses as well as a function of the pulse-front distortion. It is shown that a...

    Abstract. Many materials are good candidates for diode-pumped ultra-short-pulse lasers: several transition-metal-iondoped crystals can or could support extremely short fs pulses. This goal, so far, has only been reached by Cr[sup 3+]:LiSAF, but there are good chances for other crystals like...
