We demonstrate high-power longwave mid-IR ultrafast sources based on a Er-fiber laser system at 1.55 µm with 32-MHz repetition rate. Compared previous 1.03-µm-driven difference frequency generation (DFG), our current configuration allows tighter focusing in the GaSe crystal thanks to an increased damage threshold µm. Consequently, 1.55-µm-driven DFG can operate regime of optical parametric amplification (OPA), which power grows exponentially respect square root pumping power. experimentally...
We demonstrate a pre-chirp and gain jointly managed Yb-fiber laser that drives simultaneous label-free autofluorescence-multiharmonic (SLAM) medical imaging. show amplifier produces high-quality compressed pulses when the seeding exhibit proper negative pre-chirp. The resulting source can generate 43-MHz, 34-fs centered at 1110 nm with more than 90-nJ energy. apply this ultrafast to SLAM imaging of cellular extracellular components in various human tissues intestinal adenocarcinoma, lung liver.
We report a novel 795 nm VCSEL with longitudinal three coupled cavity. Because of large increasing the photon lifetime, spectrum linewidth has been reduced to be 7.3MHz (limited by resolution) which is near natural atomic linewidth. The additional epitaxial cavity spacers yield high diffraction losses for higher order transverse modes. High single mode output power 4.6mW was obtained under 25°C. Rigorous coupled-wave analysis (RCWA) developed and applied analyze surface grating. integrated...
Flexible pressure sensors provide a promising platform for artificial smart skins, and photonic devices new technique to fabricate sensors. Here, we present flexible waveguide-based optical sensor based on microring structure. The is five-cascade array structure with size of 1500 µm × 500 uses the change in output power linearly characterize acting device. results show that device has sensing range 0-60 kPa sensitivity 23.14 µW/kPa, as well ability detect pulse signals, swallowing, hand...
Extracorporeal circulation (ECC) catheters have potential to be blood compatible and could used prevent thrombotic occlusion. Here, we produced heparin-mimicking anticoagulation PVC tubing on a large scale by synthesizing polymer (HMP) co-extruding. The PVC@HMP catheter was evaluated using whole human in vitro, which indicated it plasma protein attachment, reduce platelet adhesion activation, inhibit coagulation factors (XII, XI, IX, VIII). Moreover, the assembled into extracorporeal with...
Polymer materials have the advantages of a low Young's modulus and low-cost preparation process. In this paper, polymer-based optical waveguide pressure sensor based on Bragg structure is proposed. The change in wavelength output spectrum grating (WBG) used to linearly characterize acting device. WBG was developed through polymer film process, experimental results show that signal device has sensitivity 1.275 nm/kPa with measurement range 0-12 kPa an accuracy 1 kPa. indicate already...
This article utilizes the Canny edge extraction algorithm based on contour curvature and cross-correlation template matching to extensively study impact of a high-repetition-rate CO2 pulsed laser target tracking performance an infrared imaging detector. It establishes quantified dazzling pattern for lasers systems. By conducting damage experiments, detailed analysis normalized correlation between images is performed quantitatively describe effects. Simultaneously, evaluation system,...
System status of a PET scanner changes slowly but continuously with environment and aging detectors. To achieve the best imaging quality, this natural change should be compensated correctly. The traditional approach is to perform detector calibration periodically. An important normalization which estimating sensitivities lines response (LORs) usually at frequency several months. It obvious that between two adjacent calibrations, mismatch factors current system become larger may lead...
The force dependence of receptor–ligand bonding has been extensively studied in biophysics. Microcantilevers are a type spring‐based sensor and their spring constants were characterized using different methods to check that the measurements consistent. made from E‐glass fibers with nominal diameter 4 μm lengths 3–7 mm mounted viewing chambers imaged under microscope 100× oil immersion lens. Multiple sets images for each microcantilever captured at 50–800 frames per second analyzed custom...
Introduction Purpose: Among young adults and adolescents, the most common malignant bone tumor is osteosarcoma (OS). Even patients who are cured by surgery or neoadjuvant chemotherapy still have a high possibility of recurrence. In recent years, due to development molecular biology research methods, many new prognostic markers based on gene level emerged. addition, mutual regulation mode among long non-coding RNA (lncRNA), miRNA target genes closely related occurrence tumors. our research,...
