This method of removal is less time-consuming compared to the other two methods and the parameters are easier to control. Regarding laser processing, the precision lens on the laser processing phosphatase inhibitor platform tends to age, which may affect the accuracy of the moving platform and lead to cause experimental errors. This can also lead to inferior processing results, problems such as an inability to correctly remove materials, and/or changes in the material properties and costs of heating the area because of excessive laser energy [11,12]. However, regardless of which method is employed, they all provide the same disadvantage, Inhibitors,Modulators,Libraries that is, a lack of comprehensive post-processing quality control procedures.

Based on the above discussion, and to further understand the basic characteristics of window-type optical fiber sensors, we used CO2 laser processing Inhibitors,Modulators,Libraries as the fiber optic sensor processing method in this study because the laser-processing parameters are convenient to configure and provide a wider range of basic characteristics. Studies of common optical fiber sensors typically investigate only fiber optic sensor fabrication methods or the resolution and sensitivity of back-end sensing applications; the processing quality of the sensing area is rarely examined [13, 14 and 15]. Poor-quality processing, such as over-processing resulting in excessive removal or modification Inhibitors,Modulators,Libraries of material, can reduce the sensor resolution Inhibitors,Modulators,Libraries and sensitivity, cause light scattering in the sensing area, insufficient sensing power, or functional surface coverage during subsequent surface plasmon resonance (SPR) or particle plasmon resonance (PPR) detection [16,17].

Therefore, the purpose of this study was to eliminate defects or residue from the sensing area of window-type optical fiber sensors. We examined the CO2 laser processing results for the Entinostat sensing area and established a CO2 laser processing quality inspection method. Finally, a window-type optical fiber sensor was developed according to the optimal processing conditions identified in this study, and the sensor performance was subsequently verified.2.?Experimental SectionThe adjustable parameters of the CO2 laser machine (Model Mercury-II M-12, LaserPro Inc., New Taipei, Taiwan) employed in this study included the processing power (1 W to 10 W), processing speed (0.63 cm/s to 63 cm/s), laser-sourced cooling nozzle pressure (0.

1 MPa at less than 60 psi), and focusing position (adjusted by altering the Z-axis in the machine’s three-axis displacement platform). The non-adjustable parameters were the laser pulse width (��0.2 ��s) and pulse frequency (5 KHz). This study primarily selleck chemicals analyzed the sensing area quality of laser-processed optical fiber sensors. To conduct various quality analyses more accurately, we set the fixed length of the sensing region to 1 cm, the focusing position on the fiber core to 0.1 mm, the laser pulse width to 1 �� 0.2 ��s, the laser pulse frequency to 5 KHz, and the air nozzle gauge pressure to 0.
