Practical Mid-infrared Dual-comb Spectroscopy with Absolute Frequency Referencing Based on a Single-cavity Dual-comb Fiber Laser
Akifumi Asahara, Kaoru Minoshima
We demonstrate a practical mid-infrared (MIR) dual-comb spectroscopy (DCS) method based on a bidirectional dual-comb fiber laser. By exploiting the inherently high relative stabili…
Laser-scanning optical-frequency-comb microscopy for multimodal imaging
Shimpei Kajiwara, Eiji Hase, Shota Nakano +9
We introduce a novel laser-scanning optical microscopy technique that employs optical-frequency-comb (OFC) lasers. This method facilitates multimodal spectroscopic imaging by analy…
Optical phased array using phase-controlled optical frequency comb
Takashi Kato, Kaoru Minoshima
We developed an optical phased array using an optical frequency comb and demonstrated its proof-of-principle. Optical phased arrays have been actively developed in recent years as…
Jones-matrix dual-comb spectroscopic polarimetry
Hidenori Koresawa, Hiroki Kitahama, Shogo Tanimura +6
Spectroscopic polarimetry (SP) is a powerful tool for evaluation of thin film, optical materials, and biological samples because it can provide both polarimetric and spectroscopic…
