Recently, highly stable molecular iodine Raman laser operation on more than 150 lines between 544 nm and 1330 nm has been demonstrated [1]. As pump source a cw frequency doubled monolithic Nd:YAG laser with an output power up to 500 mW is used. To enhance the interaction length with high intensity, experiments with iodine filled hollow waveguides have been started. Lasing in waveguides with 200 µm inner diameter and 50 cm length in standing wave resonators with thresholds below 40 mW have been achieved so far. Investigations on these novel resonator configurations in comparison to conventional setups will be reported.
