Diode laser controller DLC202/DLC252/DLC502
The MOGbox DLC202 laser diode controller is the world's first all-in-one controller for driving and frequency locking an external cavity diode laser. Every model includes:
All in one box, based on a single 10-layer PCB (plus the external photodetector and protection/connection circuit board for the laser head).
The ultimate controller for single-frequency diode lasers

2、Tunable cateye Lasers
Cateye diode laser CEL002
The MOGLabs cateye diode laser offers a new twist in external cavity diode lasers. A cateye reflector and ultranarrow filter replace the alignment-sensitive diffraction grating of conventional Littrow and Litman-Metcalf designs.
The CEL002 is robust, stable, and acoustically inert. You can literally hit it with a hammer and it will stay locked, and it is inherently self-aligning so you can tune tens of nanometres without having to realign. In combination with MOGLabs electronics, the linewidth can be well below 100 kHz. Most laser diode wavelengths are available, for example 393 to 400, 423 to 426, 460, 470, 638, 647, 671, 739 to 800, 820 to 895, 920 to 935, at powers up to 200mW extra‐cavity.
CEF extended cateye diode laser
The MOGLabs cateye diode laser is also available in an extended chassis which allows internal mounting of a Faraday isolator, and single-mode fibre coupling. Fibre coupling is extremely simple and stable using two mirrors (or one mirror and PBS beamsplitter cube, for access to a second beam for frequency stabilisation). We typically use Schafter+Kirchhoff couplers as shown but can also use Thorlabs FiberPort adapters. Coupling efficiency is over 70% with near infra-red diodes.
3、Tunable Littrow Lasers
Littrow extended cavity diode laser ECD004
Our latest research-quality Littrow configuration extended cavity diode laser with monoblock chassis. Machined from a solid block of aluminium alloy, this laser is compact (105x90x90mm), robust and stable. With a standard (uncoated) 780nm diode, the laser will scan modehop-free at least 15GHz (in some cases up to 40GHz). The linewidth is routinely below 200kHz and can easily achieve sub-100kHz.
The diode is user-changeable and we even include a free† spare!
Some common configurations:
MOGLabs offers a vast array of wavelengths including, but not limited to, 369.5nm, 399nm, 405nm, 413nm, 422nm, 461nm, 492nm, 639nm, 657nm, 671nm, 689nm, 767nm, 770-820nm, 852nm, 866nm, 960nm, 1033nm, 1092nm...just ask us!

4、RF synthesizers and AOM drivers
The MOGLabs ARF421 AOM driver provides two channels of agile RF frequency synthesis with
optional high-power output drivers. Built-in PID feedback servo allows simple application as an optical power noise eater. Uses AD9910 DDS cores, a high-speed FPGA, and separate microcontrollers for communication and control.

The MOGLabs SAS021/SAS421 uses enhanced DDS devices (AD9914) for faster and higher resolution RF control. We expect customer-ready product in 2017.

Optical amplifier MOA002
The MOGLabs amplifier is a low-cost tapered amplifier for use with single-frequency external cavity diode lasers. Laser power is increased by up to 2W, while maintaining the tunability and linewidth of the injection seed laser. Replacement of the amplifier diode and alignment are easily accomplished by the end-user. Wavelength options extend from 630nm to 1064nm, and powers up to 2W.
6、Laser and controller accessories
The photodetector supplied with MOG controllers is available separately. In standard configuration, it provides a balanced differential Si-PIN photodiode pair, with 720kHz bandwidth (–3dB) and very low noise. Standard photodiode options include 350nm–1120nm, 400–1100nm or 740–1100nm (solar blind) sensitivity, ±10, 20 or 75° degree field of view. Dimensions are 68 × 30 × 30 mm.
°° = ±10°, ±20° ± 75° specifies the field of view
λ=400–1100nm, 740–1100nm specifies the spectral sensitivity
Our electronic driver for a very fast (sub-microsecond) mechanical shutter for laser beams, using a voice coil actuator from a hard disc drive.† The actual shutter is described in the paper Enhanced laser shutter using a hard disk drive voice-coil actuator, Rev. Sci. Instrum. 78 026101 (2007).
The shutter, and variations based on loudspeaker voice coils, relay actuators and other electromechanical devices, are easily constructed, but the electronics can be a nuisance. MOGLabsoffer an advanced version of the circuit described in the paper above, for use with any standard plugpack power supply (DC 12 to 48 V). It offers both manual (toggle switch) and TTL control, and will drive a forward or reverse current, up to 6 amps.

†Please note, we do not offer the mechanical shutter, only the electronic driver. Substantial information regarding mechanical shutters is availablehere.
Several accessories can be provided for our diode laser controllers and laser heads, such as AR-coated diodes, Faraday isolators, vapour cells, headboards, Zeeman modulation coils, and more.
