Tunable Diode Lasers

CTL – Continuously Tunable Laser

  • Mode-hop-free tuning up to 110 nm
  • Available at 950, 1050, 1320, 1470, 1500 and 1550 nm
  • Up to 80 mW output power
  • High resolution and wavelength accuracy
  • User friendly touch screen, buttons and remote control

The CTL is the ultimate choice when looking for a laser that is widely tunable without any mode-hopping. It has high power, a narrow linewidth and high absolute and relative wavelength accuracy. Wide scans can be performed with highest resolution. With the fully digital, low noise and drift DLC pro controller, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language.

 

DL ProDL pro – Tunable Diode Laser

  • Tunable diode laser in patented pro technology
  • Available with four exceptional AR diodes
  • Ultra stable against temperatures & acoustics
  • Low drift, narrow linewidth
  • Easy coarse & fine tuning

Our DL pro is the ultimate tunable diode laser. Its revolutionary mechanical design allows for both easy operation and extreme stability at the same time. The underlying Littrow geometry stands for highest output powers, and optimum mode-hop free tuning is realized with a perfectly positioned virtual pivot point for the grating movement. Patents: DE 10 2007 028 499 and US 7970024.

Other wavelengths are available from DL 100 / pro design with the same “pro” mechanics but a larger variety of laser diodes.

 

DL 100DL 100 – Tunable Diode Laser

  • Economic, tunable cw diode laser
  • Widest wavelength selection: 370 nm .. 1770 nm
  • Output powers up to 300 mW
  • Modular design with hands-on set-up

TOPTICA’s DL 100 is a well-established and economic laser source for spectroscopy and many other scientific applications. It is an open system that can be changed and maintained by the experienced user. The DL 100’s specifications depend strongly on the implemented laser diode and are given in TOPTICA’s laser diode stock lists.

 

DL 100 pro HPDL pro HP – Tunable and Powerful

  • Up to 100 mW single-frequency, tunable output
  • Standard wavelengths 405, 425, and 633 nm
  • Other wavelengths 370 .. 640 nm on request
  • Extremely stable, low drift
  • Linewidth < 2 MHz

The DL pro HP diode laser features a special resonator design, which allows for higher single-mode output powers from “visible” laser diodes. Manual coarse tuning of the wavelength is possible across the gain spectrum of the diode (for blue diodes approx.  2-3 nm) and mode-hop free fine tuning up to 50 GHz. Standard models are available at 405, 425 nm, and 633 nm; other wavelengths between 370 and 640 nm can be provided on request. The laser features various modulation inputs and includes an isolator. Fiber coupled versions are optionally available.

DL DFBDL DFB – Distributed Feedback Lasers

  • Single-frequency laser with distributed feedback diode
  • Any wavelength between 760 nm .. 3500 nm available
  • Largest mode-hop free tuning range: Up to 1400 GHz
  • Reliable operation even in harsh environments
  • Options: High-frequency modulation, fiber output

Distributed feedback (DFB) lasers offer wide frequency tuning and high output power in a compact, rugged setup. The frequency selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures single-frequency operation without any bulk optics. A wide variety of DFB diodes is available from stock; custom wavelengths can be provided even in low quantities. Available DFB diodes.
