Design and characterization of a low-cost cateye laser for scientific applications — •Shubha Deutschle, Simon Schuster, Philip Wolf, Max Eisele, Sonja Lorenz, Claus Zimmermann, József Fortágh, and Andreas Günther — Center for Quantum Science, Physikalisches Institut, Eberhard Karls Universität Tübingen, Auf der Morgenstelle 14, D-72076 Tübingen

For various applications in quantum optics, tunable lasers with single mode operation, narrow linewidth and high mechanical stability are required. We show the setup and design of an affordable external cavity diode laser, which meets these requirements using a retroreflective system, an interference filter and wedge prisms for easy adjustment of the beam path. The laser is equipped with a self-build electronic board, holding a diode protection circuit and a frequency modulation unit. With a bandwidth of 40MHz, it can be used for multiple laser locking schemes. We measure the linewidth of the laser, using a self-heterodyne interferometer, to be 50 kHz.
