[HTML][HTML] A pressure-tuned Fabry Pérot interferometer for laser frequency stabilization and tuning
We present a simple, inexpensive pressure-tuned Fabry Pérot interferometer which can be
used to frequency stabilize and tune a laser when no suitable atomic reference is available.
Our design, made largely from off-the-shelf parts, yields a tuning range of about 4 GHz and
offers an absolute tuning accuracy of better than 1 MHz. The interferometer, which uses air
as its working medium, is characterized by a low thermal drift rate of order 1 MHz per hour.
