Frequency noise MDL pro vs. DL pro
MDL pro
Modular Tunable Single-Mode Diode Laser System for 19" rack integration
- Up to 4 lasers in DL/DFB pro configuration
- Spectral coverage 369 .. 1770 nm
- Low noise and drift, narrow linewidth
- Light delivered by single-mode PM optical fibers
- Digital control via DLC pro for best performance and convenience
The MDL pro combines up to four narrow-linewidth tunable diode lasers in a compact 19” sub-rack and seamlessly integrates into the T-RACK or other suitable 19” racks. This solves many challenges of modern atomic optics: It simplifies laser operation with all integrated lasers being controlled from a single unified interface. Furthermore, it helps to clear optical tables and to stow away lasers into a 19" form factor. Thereby, it enables researchers to focus on their experiment rather than on their laser system. Please see Laser Rack Systems for the complete product family.
MDL pro modular laser systems achieve the same ultimate performance as TOPTICA’s established DL pro or DFB pro series: Unprecedented passive stability, unique locking solutions and narrow linewidth.
The MDL pro integrates tunable single-mode laser modules at wavelengths between 369 and 1770 nm. These modules are based on TOPTICA's DL pro or DFB pro lasers. Up to four individual modules can be selected and combined freely in the MDL pro. All laser diodes from TOPTICA stock lists are available.
The MDL pro modular laser unit features a full-extension pull-out mechanism ensuring easy access to the laser modules. Moreover, it offers passive vibration isolation decoupling the lasers from the environment. The unit is highly compact consuming only 2 RU in height. An additional 1-RU space is recommended for thermal isolation between different laser units. Optical output is fiber-delivered allowing for flexible laser light delivery wherever required.
The MDL pro laser modules are controlled with TOPTICA’s DLC pro. Its digital architecture enables low-noise laser operation, intelligent locking functions and remote control via Ethernet.

Specification
The MDL pro may be included in a T-RACK and therefore be part of a complete Laser Rack System. In this case, one takes full advantage of the integrated rack solution. The MDL pro may also be purchased for mounting in a standard 19" rack by the customer. A regular 4-post rack with 600 mm or 800 mm depth (post separation between 500 mm and 700 mm) is required. Space requirements in the rack vary depending on the specific configuration. One unobstructed height unit has to be added below each module (MDL pro, DLC pro) for proper thermal managmenent. For details on rack requirements please contact TOPTICA. Finally, the MDL pro may also be used as a table-top solution consisting of one laser subrack and one or two DLC pro subracks.
