  • Spectral beam combining of a 980 nm tapered diode laser bar
    [作者:Vijayakumar, D; Jensen, OB; Ostendorf, R; Westphalen, T; Thestrup, B,期刊:OPTICS EXPRESS, 页码:893-898 , 文章类型: Article,,卷期:2010年18-2]
  • We demonstrate spectral beam combining of a 980 nm tapered diode laser bar. The combined beam from 12 tapered emitters on the bar yielded an output power of 9.3 W at 30 A of operating current. An M-2 value of 5.3 has ...

  • Modulation instability in high power laser amplifiers
    [作者:Rubenchik, AM; Turitsyn, SK; Fedoruk, MP,期刊:OPTICS EXPRESS, 页码:1380-1388 , 文章类型: Article,,卷期:2010年18-2]
  • The modulation instability (MI) is one of the main factors responsible for the degradation of beam quality in high-power laser systems. The so-called B-integral restriction is commonly used as the criteria for MI cont...

  • Supercontinuum generation in a high index doped silica glass spiral waveguide
    [作者:Duchesne, D; Peccianti, M; Lamont, MRE; Ferrera, M; Razzari, L; Legare, F; Morandotti, R; Chu, S; Little, BE; Moss, DJ,期刊:OPTICS EXPRESS, 页码:923-930 , 文章类型: Article,,卷期:2010年18-2]
  • We demonstrate supercontinuum (SC) generation at both 1550 nm and 1288 nm in a compact (< 5mm(2)) 45 cm spiral waveguide composed of CMOS-compatible doped high-index glass. While both wavelengths have weak dispersion and...
  • High-order temporal coherences of chaotic and laser light
    [作者:Stevens, MJ; Baek, B; Dauler, EA; Kerman, AJ; Molnar, RJ; Hamilton, SA; Berggren, KK; Mirin, RP; Nam, SW,期刊:OPTICS EXPRESS, 页码:1430-1437 , 文章类型: Article,,卷期:2010年18-2]
  • We demonstrate a new approach to measuring high-order temporal coherences that uses a four-element superconducting nanowire single-photon detector. The four independent, interleaved single-photon-sensitive elements parse...
