Toptica DL Pro: Tunable Diode Laser

DLpro03

  • Tunable diode laser in pro design ECDL setup
  • Available with four exceptional AR diodes around 780 nm, 850 nm, 940 nm, and 1040 nm
  • Output powers up to 100 mW
  • Ultra stable, typical linewidth 100 kHz (5 µs)
  • Very low drift with room temperature changes (typ. << 100 MHz/K)
  • Insensitive to acoustics and vibrations
  • Easy coarse tuning up to 100 nm
  • Mode-hop free  tuning up to 50 GHz (optimized virtual pivot point)
  • Beam angle compensation mirror included
  • Fast AC and DC current modulation included

The DL pro is the ultimate tunable diode laser. Its revolutionary mechanical design allows both easy operation and extreme stability at the same time. The underlying Littrow geometry allows for highest output powers, and optimum mode-hop free tuning is realized with a perfectly positioned virtual pivot point for the grating movement.
