Adela Ben-Yakar is an Israeli biomedical engineer who is the Harry Jr. L. Kent Endowed Professor in the Department of Biomedical Engineering at the University of Texas at Austin. Her research uses the tools of photonics to address challenges in medical diagnostics and therapeutics.
Schematic diagram of a typical laser, showing the three major parts. A laser is constructed from three principal parts: An energy source (usually referred to as the pump or pump source), A gain medium or laser medium, and; Two or more mirrors that form an optical resonator.
Fiveable, an online learning community for high school students, made its first-ever acquisition earlier this week: Hours, a virtual study platform built by a 16-year-old. Fiveable is a free ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Engineering the laser detuning in this way to a specific red shifted value is the basis for Doppler cooling. For high-intensity lasers, power broadening occurs, altering the effective linewidth. The Rabi frequency ( Ω ) {\displaystyle (\Omega )} quantifies the strength of the atom-laser coupling and is related to detuning by the generalized ...
If the temperature of the laser is changed, then the index change of the DBR structure causes a shift in its peak reflective wavelength and thus the wavelength of the laser. The tuning range of such lasers is typically a few nanometres, up to a maximum of approximately 6 nm, as the laser temperature is changed over ~50 K. As a rule of thumb ...
Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites .
