Abstract
The paper reports on iodine-stabilized Nd:YVO4 laser with a digital controller to stabilize the laser frequency to molecular iodine. With intracavity frequency doubling using a KTP crystal, a 532 nm output is generated. The laser frequency can be tuned over a large range by temperature tuning of the KTP crystal, which acts as a Lyot filter. Furthermore, the laser frequency can be tuned over a range of about 15 GHz with a piezo-actuator (PZT). Another PZT is used for stabilization of the frequency. The laser is stabilized to saturated molecular iodine using Doppler-free spectroscopy and 3f modulation.
