Laser Treatments for Pigmentation The science behind the function of laser treatment is ‘selective photothermolysis’ which signifies the ability of a laser to regulate light frequency leading to heat production by destroying the selective tissue. There are various wavelengths of light, one of which is chosen as per the color shade of skin/hair as the case may be. Know more: https://www.sakhiyaskinclinic.com/laser-treatment-for-pigmentation/

Features: Multi-wavelength multiplexing/high-speed long-distance transmission/optical layer monitoring and management. Coarse wavelength division multiplexing (CWDM): The wavelength interval is 20nm. With the development of technology, more and more optical signals can be multiplexed, and dense wavelength division multiplexing technology has emerged. Dense wavelength-division multiplexing (DWDM): Wavelength interval is less than 0.8nm. OTN - Optical Transport Network Optical Transport Network (OTN) is defined by recommendation G.709, provides a network-wide framework that adds SONET/SDH-like features to WDM equipment (also known as Wavelength Switched Optical Network equipment, or WSON equipment). It creates a transparent, hierarchical network designed for use on both WDM/WSON devices and TDM devices. It provides an efficient way to transport, switch, and multiplex different services onto high-capacity wavelengths across the optical network.

Ultrasound Transducers in Focused Ultrasound: Revolutionizing Medical Treatment The sound waves that vibrate louder than the human hearing range are known as ultrasounds. These have shorter wavelengths, beginning at 20 kHz. The majority of ultrasonic transducers operate at frequencies with ultrasound wavelengths that begin at 20 kHz.
