We report on the frequency stabilization of an infrared (IR) laser emitting at 1.5 μm onto molecular iodine hyperfine transitions at 514 nm. Third harmonic generation process based on Periodically Poled Lithium Niobate non linear crystals (PPLN) is used to link the IR emission to the green region. We have developed and tested a compact experimental setup using a multi-pass iodine cell in order to...
Following various works on second harmonic process using periodically poled Lithium Niobate crystals (PPLN), we report on the performances comparison between commercial bulk and proton-exchanged waveguide crystals operating at 1029nm. We use a continuous wave (CW) amplified Yb doped single fiber laser delivering up to 500mW in single mode regime. In case of bulk crystal we generate 4mW using 400mW...
