Optical tweezers using a diode laser
WebJun 15, 2002 · We present a novel and direct technique to map the incident laser intensity across the active area of a spatial light modulator (SLM) by using diffraction based setup in a holographic optical tweezers (HOTs) system to generate structured light. The incident laser beam profile on the SLM is used as input to the optical trap generating algorithms … http://216.92.172.113/courses/phys39/laser%20tweezers/Optical%20Tweezers%20Using%20A%20Diode%20Laser%20(GOOD!).pdf
Optical tweezers using a diode laser
Did you know?
WebAn optical tweezers apparatus uses a tightly focused laser to generate a trapping force that can capture and move small particles under a microscope. Because it can precisely and non- destructively manipulate objects such as indi- vidual cells and their internal components, the optical tweezers is extremely useful in biolog- ical physics research. WebThe possibility for the manipulation of many different samples using only the light from a laser beam opened the way to a variety of experiments. The technique, known as Optical Tweezers, is nowadays employed in a multitude of applications demonstrating its relevance. Since the pioneering work of Arthur Ashkin, where he used a single strongly focused laser …
