DLC pro

All digital controller for tunable diode lasers

  • Extremely low noise & precise control
  • Knobs & touch user interface
  • Remote PC GUI & command control
  • Intelligent locking features

DLC pro is the new benchmark for diode laser controllers. It defines a new level of low noise and convenience. Its low noise and drift levels make our DL pro series lasers even more silent and stable. Its impressive resolution (23 bits and more) enable precise control, and its knob/touch user interface and PC GUI allow for the most comfortable and intuitive operation. Easily change scan parameters with a multi-touch gesture to zoom onto spectral features or use the included FFT to analyze signals.

With the intelligent locking option DLC pro Lock installed, you may select a spectral feature by taping on it on the screen and locking the laser to that peak with a simple press of a button. The intelligent locking option includes a 2-channel digital PID loop (bandwidth about 30 kHz), modulation and demodulation (11 Hz to 160 kHz) and ReLock. It allows for top-of-fringe as well as side-of-fringe locks with easy optimization of the PID parameters. The features are enabled with a software license.

If this license is not purchased along with the DLC pro, the license-protected features may be tested with the 30-day trial license provided with the DLC pro. A license for your device without time limit may then be purchased later. Activating by entering a license-key is an easy procedure that may be done by the customer.

For all systems, it is possible to stabilize the power of the laser system by controlling the current of the laser diode (DL pro, CTL) or the tapered amplifier chip (TA pro, TA-SHG pro, TA-FHG pro) using an external photodiode (all systems) or an internal photodiode (CTL, TA pro, TA-SHG pro, TA-FHG pro).  Bandwidths in the kilohertz regime are achieved (see CC-500 and CC-5000 sections in the specifications below).

The DLC ext allows extending the DLC pro with TOPTICA’s well-established fast locking modules. These modules provide high performance laser locking if a faster feedback than available with the DLC pro Lock option is needed.
