Precise control of a laser diode’s wavelength is necessary for atomic research. A laser housing is used to provide precise mechanical control of the wavelength. Typically, these housings are either commercially purchased or milled from metal. We also designed a 3D printed housing for a laser tunable at 1015 nm whose performance was tested using atomic spectroscopy and found to be comparable to the metal housing while being a fraction of the cost. We also used atomic transitions to confirm the laser properties of a commercially purchased laser tunable at 1529 nm through a process called Electromagnetically induced transparency (EIT).
