- For Integration in the T-RACK or in a 19" Standard Rack
- Narrow Linewidth
- Tunable & Frequency Lock
- Light Provided by Single Mode PM Fibers
- Digital Control DLC pro for Best Performance
The MDL pro combines up to four narrow-linewidth tunable diode lasers in one compact sub-rack. This solves many problems of modern atomic optics: It simplifies complex operations because all integrated lasers are controlled using only one unified interface. Furthermore, it clears optical tables and stows away the lasers in a 19" standard subrack. This enables researchers to focus on their experiment instead of the laser system. The MDL pro is also transportable which fulfills the need of next-generation AMO systems and supports further compactification and mobilization of state-of-the-art lab-based experiments. Please see Laser Rack Systems for the complete product family and T-RACK for a suitable rack.
The MDL pro is a 2U 19" rack element that integrates tunable single-mode laser modules at wavelengths between 369 and 1625 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 integrated lasers of the MDL pro achieve the same ultimate performance as TOPTICA's established DL pro or DFB pro series: Unprecedented passive stability, unique locking solutions and narrow linewidth. Each laser is fiber-coupled (using FiberDock) independently to allow for flexible integration into existing setups. A drawer slide design enables quick access and easy service.
The laser modules of the MDL pro are controlled with TOPTICA's DLC pro. With a touch screen, knobs and buttons this 3U laser controller enables a unique user convenience, combined with a low-noise operation and intelligent locking functions due to its digital architecture. It also enables a remote control of the integrated laser modules.
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.

- Lock Option for DLC pro: Software license that enables a number of features on a specific DLC pro. These allow to control the frequency of a laser for example by using a saturated absorption spectroscopy setup with a reference cell.
- Electronics Modules: A broad variety of electronic locking modules is available for frequency stabilization.
