Selective laser vaporization of polypropylene mesh in tissue

  Motivation for the study Surgical mesh is used to treat female stress urinary incontinence (SUI) and transvaginal pelvic organ prolapse (POP). However, erosion of this synthetic, non-absorbable mesh is a common complication and in more than half of these cases, a surgical excision of the mesh in the operating room is required. The mesh removal is technically challenging, may damage healthy adjacent tissues, and in some cases must be repeated several times. This study aims to explore the feasibility of selective laser vaporization, which Continue reading →Customer case University of North Carolina at Charlotte is a public research university founded in 1946. Department of Physics and Optical Science is dedicated on developing minimally invasive optics solutions for biomedical indications, such as tissue ablation, nerve simulation and surgical applications. Collaborations with Carolinas Medical Center at Charlotte and John Hopkins University at Maryland. Most recent research activities have focused on development of thulium fiber laser (TFL) as an alternative to the gold standard Holmium: YAG laser for lithotripsy (destruction of kidney stones), and Continue reading →

Range Finding

    Laser range finding applications set several requirements for the laser device. High output power is required at the same time in very short pulses of even picosecond range. However, the required power is defined by the distance and reflectivity of the target. High power can be achieved by constructing several emitter stacks or by increasing a single emitter dimensions. Light pulses up to 120-150 Watts can be generated using Modulight’s laser diodes at 905 nm wavelength range. Though comparably lower output power with Continue reading →Laser range finding: How it works? Pulsed laser range finder is based on measuring the difference in properties of the transmitted and back-reflected light from the target. The target changes the properties of the incident light and the back-reflected light is analyzed in the receiving equipment. Modulight manu­factures range-finding lasers for various market segments. The distance measurement techniques are required in determining the height, width, distance, volume or movement of the target.  Applications for the technique are laser radar speed measurements, traffic safety, laser profiling Continue reading →
