TA pro

Tapered Amplifier Laser System

    • MOPA configuration in pro technology
    • Wavelengths between 660 nm and 1495 nm
    • High power, up to 4 W
    • Stability and Ease of Use of pro technology
    • With all-digital DLC pro electronics

    The TA pro is the flagship product of TOPTICAs high power tunable diode laser solutions.  Its tapered amplifier technology allows for high power with excellent beam quality, while at the same time maintaining the favorable spectral properties of the pro master laser. The TA pro is a completely revised version of a very well-established laser system, the TA 100. It has been optimized for extreme stability and ease of use, and has proved these properties in numerous tests in TOPTICAs and customers´ laboratories.

    The DLC TA pro is equipped with TOPTICA's all digital DLC pro control electronics: with lowest noise and drift and more convencience, it also offers highest amplifier currents up to 10 A and additional protection for the amplifier chip. Also available with the economic SYS DC 110 laser electronics.

    • Additional Information
    • Options

      Optical Isolation Single Stage
      Isolators are used to protect the laser diode from back reflections. This not only prevents damage to the diode but also ensures untroubled single-mode operation and tuning. Fiber coupling with angle polished fibers (both ends) requires at least a single stage isolator.
      Optical Isolation Double Stage
      Double stage isolators are needed if reflections from the experiment into the laser are expected. Fiber coupling with non-angle polished fibers also requires a double stage isolator.
      TOPTICA's patented fiber coupler provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability. TOPTICA additionally offers a wide range of single-mode and polarization maintaining fibers, including fiber-optic beam splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
      Locking and other electronics modulesFor DLC pro, the versatile DLC pro LOCK option is available. With DLC ext and for SYS DC 110 electronics, TOPTICA offers a large range of control, stabilization and frequency locking modules.
      DFB master
      Optionally, a DFB master laser can be implemented for wide mode-hop-free tuning.
