Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. [1] This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode.
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
Sex therapy is a therapeutic strategy for the improvement of sexual function and treatment of sexual dysfunction.This includes dysfunctions such as premature ejaculation and delayed ejaculation, erectile dysfunction, lack of sexual interest or arousal, and painful sex (vaginismus and dyspareunia); as well as problems imposed by atypical sexual interests (paraphilias), gender dysphoria (and ...
Low-intensity extracorporeal shock wave therapy has been used as a treatment for erectile dysfunction. [23] It differs from palliative options by aiming to restore natural erectile function by inducing cellular microtrauma, triggering the release of angiogenic factors and promoting neovascularization in treated tissue. This mechanism is ...
In 2004, a pulsed electromagnetic field system was approved by the FDA as an adjunct to cervical fusion surgery in patients at high risk for non-fusion. [6] On 8/9 September 2020 the FDA recommended to shift PEMF medical devices from the Class 3 category to a Class 2 status. [7]
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).
Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level, with the laser pulse being stretched out temporally and spectrally, then amplified, and then compressed again. [1]
