Mid infrared gas spectroscopy using efficient fiber laser driven photonic chip-based supercontinuum.

Grassani D, Tagkoudi E, Guo H, Herkommer C, Yang F, Kippenberg TJ, Brès CS.
Nature communications. 2019 04;10(1)1553.
Directly accessing the middle infrared, the molecular functional group spectral region, via supercontinuum generation processes based on turn-key fiber lasers offers the undeniable advantage of simplicity and robustness. Recently, the assessment of the coherence of the mid-IR dispersive wave in sili

Highly sensitive photoacoustic multicomponent gas sensor for SF decomposition online monitoring.

Yin X, Dong L, Wu H, Zhang L, Ma W, Yin W, Xiao L, Jia S, Tittel FK.
Optics express. 2019 Feb;27(4)A224-A234.
A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation o

消化器科領域の炭酸ガスレーザー―より安全な内視鏡的粘膜下層剥離術を目指した，炭酸ガスレーザーを用いた新たな展開―

森田圭紀,有吉隆佑,本多典広,間久直,粟津邦男
日本レーザー医学会誌 38(4), 413-420, 2018
<p>内視鏡的粘膜下層剥離術（Endoscopic Submucosal Dissection: ESD）は早期消化管癌に対する低侵襲な治療法として広く受け入れられている．しかしながら，高度な技術を要し，手技の成功は術者の腕に委ねられているのが現状である．我々はこの問題を解決するために，炭酸ガスレーザーを用いた新しい内視鏡治療器の開発を行った．炭酸ガスレーザーは水に吸収されやすいため， …
