  The circuit and PCB layout we use is a slightly modified version of the much-enhanced design from Ken Baldwin and Maarten Hoogerland at the Australian National University, Canberra, ACT. Here's their web page.
• Our old temperature controller is a modified version of a design that originates from Bill Drury at Flinders University in Adelaide, South Australia. He based it on a paper by:
  R.J.Miller and H.F.Gleeson: "A computer interfaced high-stability temperature controller and heating stage for optical microscopy" Meas.Sci.Technol. 5 904–911 (1994).
• The lock-in amplifier and AOM drivers are similar to designs that we originally found on the extremely useful electronics web pages of Steve Gensemer (Phil Gould's group). The circuits there were apparently based on designs from Kurt Gibble, although it's not clear where they really started. The phase shifter is similar to one based on bipolar transistors in Horowitz and Hill, but using FETs, e.g. as shown on page 9 of National Semiconductor's Application Note AN-32. Some description of the lock-in can be found in the following paper:
  D Milic, W Lu, MD Hoogerland, M Blackshell, KGH Baldwin and SJ Buckman: "Improved spectral properties of diode lasers", Rev. Sci. Istrum. 68 3657–3659 (1997). Note that there are some errors in this paper, including a battery connected in reverse, improper biasing of the input FET, and converting the lockin reference from a sine wave to a square wave.
