Popis: We demonstrate high-resolution spectroscopy of molecular iodine using coin-sized laser modules at 531 nm, 561 nm, and 594 nm. Hyperfine components of the R(36)32-0, P(64)20-0, and P(69)12-1 transitions are observed with a signal-to-noise ratio of several tens over a bandwidth of 100 Hz. The laser modules are frequency-stabilized to the observed hyperfine components and achieve stabilities at a level of 10−12 for a 1-s averaging time. The frequency-stabilized coin-sized laser modules are useful for various applications, including interferometric measurements and studies of molecular iodine.
