A test target bursts into flame upon irradiation by a continuous-wave kilowatt-level carbon-dioxide laser. The carbon-dioxide laser (CO 2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser.
The ultrashort pulse laser treatment may have potential applications in the disinfection of medicines, in the production of inactivated vaccines, [8] and in the possible future treatment of blood-borne viral infections from agents such as HIV and Ebola virus. [citation needed] [9]
Grating-eliminated no-nonsense observation of ultrafast incident laser light e-fields is a simplified version of FROG. ( Grenouille is French for " frog ".) Chirp scan is a technique similar to MIIPS which measures the spectral phase of a pulse by applying a ramp of quadratic spectral phases and measuring second harmonic spectra.
A TEA laser is a gas laser energized by a high-voltage electrical discharge in a gas mixture generally at or above atmospheric pressure. The most common types are carbon dioxide lasers and excimer lasers, both used extensively in industry and research; less common are nitrogen lasers. The acronym "TEA" stands for "transversely excited atmospheric".
Q-switching, sometimes known as giant pulse formation or Q-spoiling, [1] is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high peak power, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode.
Before-and-after photographs taken along the path of the total solar eclipse in North America reveal the stunning, awe-inducing nature of the celestial phenomenon.
MM underwent an endoscopic procedure to reduce her stomach size by 80% and wasn't planning to take anti-obesity medications. However, she and her doctor, Dr. Steven Batash, MD, a board-certified ...
[10] [11] In 1965, Smith and Turner [11] succeeded in depositing thin films using a ruby laser, after which Groh deposited thin films using a continuous-wave CO 2 laser in 1968. [12] Further work demonstrated that laser-induced evaporation is an effective way to deposit dielectric and semiconductor films.
