With TOPTICA’s DLC pro, high-end laser control now enters the digital world! The new digital laser controller for TOPTICA’s tunable diode laser DL pro sets new benchmarks with regards to low noise and low drift levels. It provides intuitive touch control and powerful remote operation to run and frequency stabilize the laser. Never before was the use of tunable diode lasers, e.g. for demanding experiments in quantum optics and spectroscopy, so convenient.


The DLC pro comes with laser diode current, temperature and piezo drivers with unprecedented noise and drift properties. It boosts the performance of TOPTICA’s established tunable diode laser DL pro which now runs even more stable and with lower linewidths down to 10 kHz. For active frequency stabilization, the DLC pro readily provides dual PID and lock-in control. 

The user can operate the DLC pro via knobs, buttons and a capacitive touch display. A PC software and command line interface allow remote operation via Ethernet or USB.

The DLC pro can directly display signals from the experiment replacing additional external oscilloscopes. Using the signal display, the user can intuitively adjust e.g. scan parameters via multi-touch gestures.

Complex operations like laser locking (Click&Lock) or FFT of the error signal can be performed remotely via PC or directly on the DLC pro (no PC-operation required). Advanced ReLock functions and other features from TOPTICA’s DigiLock, are integrated as well.

Experiments requiring a narrow linewidth (e.g. optical clocks or quantum computing with cold atoms and ions) as well as setups needing remote laser control (e.g. polar LIDAR) will highly benefit of the DLC pro. All other users will appreciate its intuitive and convenient operation.
