TA pro

Tapered Amplifier Laser System

  • Wavelengths between 632 nm and 1590 nm
  • High power up to 4 W
  • Low noise and drift, narrow linewidth
  • Stable and reliable with pro technology
  • Convenient touch, knob and remote control with DLC pro

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 very well-established laser system 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.

TA pro is also available as a TA pro AL with AutoAlign. TA pro AL allows integration of up to two complete MOPA systems. The AutoAlign feature can automatically optimize the coupling into the amplifier chip and fibers. For table-top TA pro AL systems, please inquire. The rack-mounted version of TA pro AL for integration in T-RACK is available as MTA pro.

With the TA pro F variant locking is faster than ever laying the foundation for the next generation quantum technology. The system features an intra-cavity EOM which provides two feedback channels. One is used for fast adjustments to ensure the superb locking performance, the other guarantees the high robustness of the lock.

  • 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.
    Fiber Delivery
    		 Fiber Delivery (FD) is optionally available with TOPTICA's patented fiber coupler FiberDock and a suitable polarization maintaining (PM) fiber. FiberDock provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability.
    For most lasers, we specify a PER behind fiber of >20 dB with our Fiber Delivery option. Please also inquire about Long Life and High Power fibers as well as fiber splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
    Locking and other electronics modules For DLC pro, the versatile DLC pro LOCK option is available as well as FALC pro and PDH/DLC pro modules. With DLC ext a number of analog locking modules is available.
    DFB master Optionally, a DFB master laser can be implemented for wide mode-hop-free tuning.
