Ultra-narrow Linewidth Lasers<\/strong><\/h4>\n

Chilas design and fabricate external cavity semiconductor lasers using its leading hybrid integration technology. They make ultra-narrow linewidth lasers <\/strong>which offer a very competitive price<\/strong> compared to lasers with similar specifications.<\/p>\n

The CT3 and CT3+ lasers have a wide tuning range<\/strong> without jumps and have an ultra-narrow linewidth<\/strong>, a unique combination<\/strong>. This allows them to have swept source functionality\u00a0<\/strong>which is perfect for a wide range of applications.<\/p>\n

<\/h2>\n
Possible Applications:<\/h5>\n

The operating wavelengths of the lasers and their possible applications are listed below. Please get in touch with one of our experts if you require a custom laser.<\/strong><\/p>\n

The tuneable CT3<\/strong> and CT3+<\/strong> lasers. Operating wavelength: 1550 nm, tuneable from 1490 nm – 1580 nm (CT3) or – 1590 nm (CT3+).<\/strong><\/p>\n

    \n
  • LiDAR<\/li>\n
  • Quantum key distribution<\/li>\n
  • Optic fibre sensor integrator<\/li>\n
  • OCT<\/li>\n
  • Telecom instrumentation<\/li>\n
  • Atomic clock<\/li>\n<\/ul>\n

    <\/h2>\n

    The fixed wavelength CF3<\/strong> laser. Operating wavelength: 1550 nm \u00b1 5 nm.<\/strong><\/p>\n

      \n
    • Optic fibre sensor<\/li>\n
    • Wind LiDAR<\/li>\n<\/ul>\n

      <\/h2>\n

      The ultra-narrow linewidth<\/strong> and the wide tunability range<\/strong> make Chilas lasers ideal for communications applications, such as Datacom and satellite communications, or for LiDAR applications in the automotive industry, robots and wind LiDAR.<\/p>\n

      \"\"<\/p>\n

      The very broad tuning range, the swept source functionality and the small footprint of the CT3 lasers all make these lasers unique. They allow you to have more sensors on a single fibre and to perform in the range of applications listed above<\/p>\n

      <\/h2>\n

      Advantages of Chilas’ Lasers:<\/h4>\n

      Low cavity loss and a long optical cavity length mean Chilas\u2019 laser can achieve high output power (>40 mW)<\/strong> and ultra-narrow linewidth (<1 kHz)<\/strong>.<\/p>\n

      The lasers are housed in a compact, 14-pin butterfly package to enable compatibility<\/strong> with any standard 14-pin laser diode mount.<\/p>\n

      The intuitive software<\/strong> has adjustable sliders to easily tune and calibrate wavelengths and adjust the output power. The software then loads the data into a .csv file for further processing.<\/p>\n

      Some of the other advantages are listed below:<\/p>\n

        \n
      • Ultra-narrow linewidth<\/li>\n
      • Very wide tuning range<\/li>\n
      • Small footprint\/size<\/li>\n
      • Proven long-term reliability<\/li>\n
      • Built-in TEC<\/li>\n
      • PM pigtail<\/li>\n<\/ul>\n
