    • openAccess   All-optical coherent pulse compression for dynamic laser ranging using an acousto-optic dual comb 

      BILLAULT, vincent; Durán, Vicente; Fernandez-Pousa, Carlos; Crozatier, Vincent; Dolfi, Daniel; guillet de chatellus, hugues Optical Society of America (2021-07-22)
      We demonstrate a new and simple dynamic laser ranging platform based on analog all-optical coherent pulse compression of modulated optical waveforms. The technique employs a bidirectional acousto-optic frequency shifting ...

    • openAccess   Bidirectional frequency-shifting loop for dual-comb spectroscopy 

      Durán, Vicente; Djevarhidjian, Leo; guillet de chatellus, hugues Optical Society of America (2019)
      We present a bidirectional recirculating frequency-shifting loop, seeded by a continuous-wave (cw) laser, to perform multi-heterodyne interferometry. This fiber-optic system generates two counter-propagating “acousto-optic” ...

    • openAccess   Optical frequency combs generated by acousto-optic frequency-shifting loops 

      Durán, Vicente; guillet de chatellus, hugues; Schnébelin, Come; Kanagaraj, Nithyanandan; Djevarhidjian, Leo; Clement Bellido, Juan; Fernandez-Pousa, Carlos IEEE (2019-12-01)
      A recirculating loop that includes an acousto-optic frequency shifter (AOFS) constitutes a versatile procedure to generate an optical frequency comb (OFC) from a continuous wave (cw) laser. This scheme, implementable with ...

    • openAccess   Optimization of acousto-optic optical frequency combs 

      Kanagaraj, Nithyanandan; Djevarhidjian, Leo; Durán, Vicente; Schnebelin, Come; guillet de chatellus, hugues Optical Society of America (2019)
      Acousto-optic optical frequency combs can easily produce several hundreds of mutually coherent lines from a single laser, by successive frequency shifts in a loop containing an acousto-optic frequency shifter. They combine ...
