The PolySense team has just published  a new article on Optics & Laser Technology journal reporting on a study of the generation of Laser-Induced Periodic Surface Structures (LIPSS) on quartz upon irradiation with linearly polarized femto-second laser pulses (pulse duration τ = 200 fs and central wavelength λ = 1030 nm). Two different regimes of Leggi di piùNew Publication on Optics and Laser Technology journal[…]

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 7.9)  reporting on a quartz enhanced photoacoustic spectroscopy (QEPAS) gas sensor designed for monitoring of ammonia (NH3) at ppb-level concentrations. The sensor is based on a novel custom quartz tuning fork (QTF) with a mid-infrared quantum cascade laser emitting at 9.55 Leggi di piùNew Publication on Photoacoustics Journal[…]

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 7.9)  reporting on an optical sensor based on light-induced thermoelastic spectroscopy for the detection of hydrogen sulfide (H2S) in sulfur hexafluoride (SF6). The sensor incorporates a compact multi-pass cell measuring 6 cm × 4 cm × 4 cm and utilizes a quartz Leggi di piùNew Publication on Photoacoustics Journal[…]
