Laser Power Supply, Amplifier, and Controllers
Vescent Controllers for Lasers & Electro-Optics
Vescent Controllers provide the lowest noise, highest bandwidth, and most flexibility of any commercially available products. From laser current drivers with a noise density of less than 100 pA/√Hz to temperature controllers with full PID loop filter reconfigurability, our unmatched performance is designed for the most demanding AMO research. Vescent understands that "excellence by design" begins with the Controllers for any lab.
SLICE:
After many years in development, the new range of touchscreen-enabled SLICE instruments are being brought to market.
SLICE-DCC
|
|
|
The SLICE-DCC is a compact, efficient CW current controller for driving pump diodes; semiconductor optical and tapered amplifiers; and diode, interband, and quantum cascade lasers. Part of the Vescent SLICE series of high-performance, economical photonic control electronics, SLICE-DCC offers two channels of low-noise current control. Proprietary self-adjusting power supply technology automatically sets the compliance voltage to as high as 12 V but no higher than necessary to drive your load‚ allowing you to drive a traditional diode or a quantum cascade laser with the same device and the same efficiency. The two channels operate independently‚ including the automatic compliance voltage. Controlled via a touchscreen or an API command set, the SLICE-DCC includes all the features you expect from your current controller: high modulation bandwidth, power leveling, interlocking, and current limiting & diode protection circuits.

SLICE-DHV
|
|
|
The SLICE-DHV is a low-noise, high-bandwidth amplifier for controlling piezoelectric transducers. Designed for controlling PZT-driven tuning elements in lasers and cavities, it interfaces easily with laser systems, allowing optimum control. The SLICE-DHV features two gain levels. The first is a traditional 20x which gives the user access to the full 0-200 V range with a 0 to 10 V input signal. The SLICE-DHV can also operate at a gain of one (in conjunction with a DC bias), allowing lower-noise control of a ±10 V range. A wide output range (0-200 V), high current capacity (±200 mA), and low noise (450 µV rms) make this amplifier ready to take on any number of high-voltage applications. Proprietary power supply technology eliminates bulky and expensive linear power supplies while maintaining low-noise performance. The SLICE-DHV supports small-signal bandwidths greater than 200 kHz and full scale (0-200 V) bandwidths of 10 Hz.

SLICE-DLC
|
|
|
The SLICE-DLC is a dual-channel precision diode laser controller. Each channel offers an ultra-low noise current source and two temperature control loops. With a current noise density less than 100 pA/√Hz, the SLICE-DLC is ideally suited for precision spectroscopy and metrology applications. Dual-stage temperature control for each channel enables sub-millikelvin stability of the diode, resulting in minimal frequency fluctuations and drift. A current servo input enables high-speed (≥10 MHz) control of the laser frequency. High-speed RF modulation enables the user to easily write sidebands onto the laser via injection current, and facilitates a PDH-style peak lock without the use of expensive lock-in amplifiers and modulators. The SLICE-DLC employs Vescent's proprietary hybrid switching / linear power supply technology to deliver unsurpassed current noise performance.

SLICE-QTC (Quad Temperature Controller)Four-channel Temperature Controller |
|
|
When you need the world's best, have the SLICE-QTC control your temperature plant. Able to control TECs or heaters, the SLICE-QTC can perform temperature stabilization of semiconductor optical amplifiers, tapered amplifiers, optical cavities, PICs, and nonlinear & photonic crystals. Auto tune enables easy loop optimization to achieve sub-milikelvin temperature performance. Widely adjustable PID corners and gain permit use with a wide variety of temperature plants. The loops can be nested or control four separate systems. The ability to set slew rate control, maximum temperature, and configurable safety outputs ensures protection of delicate photonics devices such as doubling crystals. With exceptional temperature control, safety, and convenience features, choose the SLICE-QTC and eliminate thermal instability as your limiting factor.

SLICE-OPL (Offset Phase Lock Servo)Single-Channel Offset Phase Lock Servo |
|
|
The SLICE-OPL Offset Phase Lock Servo (OPLS) is designed to precisely control and quickly adjust the frequency detuning between a master and a follower laser. The SLICE-OPL forms a complete offset lock system when combined with the D2-250 Heterodyne Module and D2-260 Beat Note Detector. The D2-250 overlaps the free-space master & follower lasers to generate the optical beat note. It then launches the beat note into a fiber for delivery to the D2-260 where it is down-converted to the RF and then delivered to the SLICE-OPL for processing. The SLICE-OPL is designed for large frequency offsets as well as offsets as low as 10 MHz, making it well-suited for stabilizing frequency combs. The SLICE-OPL will tightly lock ƒCEO, ƒopt, or ƒrep of the RUBRIComb® series of frequency combs as well as third-party combs. The SLICE-OPL has a built-in touchscreen GUI with the ability to display and manipulate the error signal and engage the lock — all without an oscilloscope.
