Optical Trapping: Method Used in Atomic Cooling Experiments
Optical trapping is a way of cooling atoms to the point where they are no longer in motion—or are trapped. One may instantly think of optical tweezers when hearing the mention of optical trapping. While ...
Laser Marking Metals: 5 Factors to Consider
Whether you are new to laser marking or have already had significant experience in laser marking technologies, it’s a quest for continuous improvement of the quality and contrasts of laser marks. ...
Laser Scar Treatment and Nonablative Techniques
Laser based therapy of scars and wounds is a relatively new technology treatment that started in the 1980s. At first, CO2 and argon lasers were used to vaporize scar tissue and lessen the texture of the ...
Digital Holography: Interferometric Imaging of Biological Samples
High Resolution Microscopy Image quality in high-resolution optical microscopy is predominately restricted by the diffraction limit– a fundamental consequence of using lenses. High-resolution ...
Counterfeit Currency Detection: UV and Magnetic Sensors
Introduction Counterfeit currency has plagued the United States economy since before the time of our founding fathers. This article will give a brief history on the origins of fraudulent money in the ...
