Must Read:

• Safety Guidelines for HeNe Lasers and Bare Laser Tubes These safety guidelines are specifically for the types of HeNe laser provided in the kits below. For general electronics safety info, see Safety Guidelines for High Voltage and/or Line Powered Equipment .

HeNe Lasers and Laser Controllers:

• Red HeNe Laser Kit 1 (Including Zeeman). Basic setups consisting of a HeNe laser tube from 0.5 to 1.0+ mW, compatible power supply, cables and ballast resistors. Zeeman adds a set of magnets to convert to two frequency laser. The longitudinal mode behavior of these tubes is not guaranteed to be suitable for stabilizing but they are suitable for most laser experiments.

• Stabilized HeNe Laser Kit 1 (Non-Arduino Version). The tube in this kit has been tested to be suitable for stabilizing. In addition to the parts in the Red HeNe Laser Kit above, it includes a thin-film heater and power supply, PBS, and photodiodes so the laser can be stabilized and used as a single frequency laser. However, it does NOT include the locking controller.

• Stabilized HeNe Laser Kit 1 with Arduino. This adds parts for an Arduiuno-based controller to the kit above.

• Deluxe Stabilized HeNe Laser Kit 2 with Arduino. The tube in this kit has an output power of at least 3 mW so that the locked power in a single mode is similar to that of the best commercial stabilized HeNe lasers.

• Stabilized Zeeman HeNe Laser Kit 1 with or without Arduino. In addition to a tube tested to be suitable for Zeeman, it includes a set of 50 rare earth magnets to be configured surrounding the tube along with additional optics for Zeeman stabilization and testing, along all the parts in the other stabilized HeNe kits.

• Micro Stablized Laser Controller 1 (µSLC1). These are parts for ONLY the Arduino-based locking controller that will work with most 0.5 to 4+ mW HeNe laser tubes.

Displacement Measuring Interferometers and Displays:

• One, Two, or Three Axis Laser Interferometer Displacement Measurement System. Complete systems for precision measurement including an HP/Agilent 5501B or 5517 laser, interferometer optics, optical receiver(s), power supplies, and µMD1 readout.

• DIY Interferometer Displacement Measurement System includes parts to construct laser and display for homodyne, heterodyne, or combined (but not at the same time) interferometer. Except for the laser tube, everything else is closer to using stone knives and bear skins. ;-)

• Micro Measurement Display 0 (µMD0) minimal implementation for homodyne interferometers using single frequency lasers as well as linear and rotary encoders and ring laser gyros. Limited performance but at ultra-low cost. Great for a course project or to just to get your feet wet in precision measurement. ;-)

• Micro Measurement Display 1 (µMD1) for heterodyne interferometers using two frequency lasers. Includes links to detailed "Heathkit™-style" assembly instructions for the SG-µMD1 PCB.

• Micro Measurement Display 2 (µMD2) for homodyne interferometers using single frequency lasers as well as linear and rotary encoders and ring laser gyros. Includes links to detailed "Heathkit™-style" assembly instructions for the SG-µMD2 PCB.

• LIPM: An Inexpensive Laser Interferometer-Based Precision Measurement System. This is not a manual but an article on what the DIY Interferometer Displacement Measurement System Kit is based on and provides more general information.

• Basic Quadrature-Sin-Cos Decoder and Quad-A-B Interfaces including optics and electronics for homodyne interferometers to drive µMD0 and µMD2.

Scanning Fabry-Perot Interferometers:

• Basic Scanning Fabry-Perot Interferometer Kit (also known as SFPI Kit 1). These are parts to construct a confocal SFPI with as FSR of ~1.75 GHz for laser wavelengths from ~590 nm to ~650 nm using your creativeness for mounting everything. ;-) An SFPI of this type is also known as a Laser Spectrum Analyzer. It includes the mirrors, PZT, and photodiodes.

• Deluxe Scanning Fabry-Perot Interferometer Kit (also known as SFPI Kit 2). This adds Thorlabs parts to simplify construction.

• Deluxe Short, Mini, Micro, and Nano Scanning Fabry-Perot Interferometer Kits. These use the same mirrors as those above, but with smaller frames to construct really compact instruments..

• Long and High Resolution Scanning Fabry-Perot Interferometer Kits. Similar to above but the mirror RoCs are from ~13 to 100 cm, generally to achieve higher resolution. These also include a few at other wavelengths.

• Universal Scanning Fabry-Perot Interferometer Kit. The ultimate SFPI kit for the mirror junkie in you life. ;-) It has parts to construct all of the confocal SFPIs, above (but not at the same time).

• Mini Laser Mode Analyzer 1 Manual (V2). mLMA1 is an Arduino-based self-contained miniature controller intended for the short Basic and Deluxe SFPIs, as well as providing readout of power in the lasing modes or output power, Zeeman split frequency, and more.

The following are not currently available as kits and are here for information only:

• Mini Laser Mode Analyzer 1 Manual (V1). This was the predecessor to mLMA1-V2. Its benefit is simplicity in hardware and especially the firmware so it can be easily hacked. ;-)

• Michelson Interferometer Experimental Setup (MIPM) This is a general Michelson interferometer implemented with commercial components like HP/Agilen optics and Thorlabs mounts, as well as custom and home-built parts. MIPM supports a variety of interferometer configurations, tests demonstrating thermal and pressure sensing, displacement measurement with µMD0, and more.

• Universal Bipolar PWM Driver 1. High efficiency Arduino-based power supply for electromagnets and the like providing continuous control of positive and negative output up to at least 2 amps depending on the DC power supply feeding it.
