External Cavity Diode Laser

thingiverse

The ability to fine-tune the frequency of an external cavity diode laser is a crucial element in undergraduate laboratories conducting atomic research. Usually, the housing for the diffraction grating and piezo is either purchased commercially or machined from metal. However, we offer a more cost-effective solution using 3D printing, a widely available tool in many physics departments. We have thoroughly tested the laser's performance using atomic spectroscopy and self-heterodyne interferometry. The impressive performance and affordability of these designs make them an attractive option for future use.
