State of the art Laser Controllers
In the search on ultra-high-precision spectroscopic techniques, ppqSense developed advanced laser drivers that met the requirements of very low current noise and high stability. In this context, the QubeCL and QubeDL lines of laser controllers were born.
The modular architecture of the Qube-family allows the user to expand their possibility, thus covering almost any typical need in terms of control and stabilization of the laser phase/frequency against a reference source, an optical cavity or a molecular transition.
Born from research
QubeCL and QubeDL have been designed for state-of-the-art scientific purposes. The patented design, developed in a research laboratory, provides the lowest current-noise of any commercially available instrument.
The modular architecture solves to problem of having large output currents with a noise level always below 1 nA/sqrt(Hz).
In general, the current-noise of commercial driver scales linearly with the maximum output current. This is not the case of QubeCL. In fact its noise scales roughly with the square-root of the maximum current, always ensuring a sub-shot-noise operation.
With Qube-family systems the current noise does not contribute to the broadening of the laser emission, thus ensuring the narrowest linewidth and the highest frequency stability.
Compact and versatile
The fully configurable and engineered QubeCL and QubeDL systems provide the versatility and the compactness of an OEM solution while keeping the ease of use of a benchtop instrument.
QubeCL and QubeDL can be fully remotely controlled, and provide a variety of autonomous control routines that allow for a stand-alone operation in completely safe conditions for the laser.
Laser Socket Module
You can embed your butterfly-packaged or HHL-packaged laser into your driver. All the signals will be internally sent to the laser. No cables around, a full control in a 10 cm2 footprint
Set the laser polarity and grounding. Send 2 independent external signals to the laser (DC to 3 MHz)
Seamlessly phase-lock you laser to an external reference. It’s easy, try and see!
Choose between 500 mA and 1 A modules, and combine them for larger current output.
Temperature stability is not an option.
QubeCL ensures <1 mK operation in any condition.
The brain of QubeCL, with USB interface and Wi-Fi or LAN options. It accepts two unipolar DC supply voltages, one for the current section and the other for the temperature section.
It is not only a base: it is the cooling unit of the QubeCL. For larger currents you will need it!
Do you need the best current driver on the market?
Choose the current driver module, and get the simplest QubeCL, together with two independent modulation inputs that allow to control the current from DC to more than 3 MHz.
Two or more current modules can be combined for higher current output.
The PLL module provides full phase-lock capabilities.
Many modules, many functions.
The Temperature Controller module provides complete stabilization of the laser.
The laser itself can be embedded into the QubeCL.
