This page has links to the various assembly, construction, instruction,
operation, and other manuals associated with my electronics and laser kits,
as well as a few that are not currently for sale but can be duplicated
relatively easily. But first since most of these involve HeNe lasers in
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
- 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
Displacement Measuring Interferometers and Displays:
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).
- Selectable FSR Scanning Fabry-Perot
Interferometer Kit 1. This one is for the SFPI nerd-type who would like
to explore the resonances in a spherical cavity that his or her professor
probably doesn't even know exist. ;-) It uses the same mirrors as the Basic
and Deluxe kits but with a adjustable mirror mounts on a
lockable carriage on a ball bearing rail and micro-positioner to be able
to quickly and easily set the cavity spacing precisely over the entire stable
range for the 4.2 cm RoC mirrors. Coming soon.
- 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 probably never
will be. They 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. ;-)
- 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.
