بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته
هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...
15 صفحه اولThe advantage of using a diode laser instead of a Q-switched laser in photoacoustic imaging of tissues
Photoacoustic (PA) imaging of biological tissues using laser diodes instead of conventional Q switched pulsed systems provides an attractive alternative for biomedical applications. However, the relatively low energy of laser diodes operating in the pulsed regime, results in generation of very weak acoustic waves, and low signal-to-noise ratio (SNR) of the detected signals. This problem can be ...
متن کاملInvestigating Pcb Processing Using Q-switched Dpss Nanosecond Green Laser
Diode pumped solid state (DPSS) Q-switched nanosecond pulsed lasers are becoming the laser of choice for a wide variety of processes in printed circuit board (PCB) manufacturing. Lasers are being used today in PCB manufacturing for via drilling, depaneling, profiling (cutting), laser direct imaging (LDI), repair, trimming, marking, skiving and other processes. The majority of these processes ar...
متن کاملScribing of ITO-coatings using a Q-switched Nd:YAG laser
This paper describes the results of optimising three process variables (control factors) to achieve a narrow line width in laser engraving of ITO conductive coatings using the Taguchi technique of experimental design. The laser used is a NEC Q-switched continuous wave (CW) Nd:YAG laser operating at a wavelength of 1.064 μm. The three process variables explored are: Q-switch frequency, speed of ...
