WebWe report a high-energy single-frequency deep-ultraviolet (DUV) solid-state laser at 167.079 nm by the eighth-harmonic generation of a diode-pumped Nd:LGGG laser. A maximum DUV laser output energy of 1.5 μJ at a 5 Hz repetition rate with a 200 μs pulse duration is achieved. The central wavelength of the DUV laser is located at … WebIn particular, high frequency radiation has a ionizing power, which means is able to remove electrons for atoms and eventually damege biological structures like the DNA. Moreover, as the frequency get higher the penetration power of the radiation increase which means that damage can be affect deeper parts of tissues.

A black light lamp emits long-wave UV‑A radiation and little visible light. Fluorescent black light lamps work similarly to other fluorescent lamps, but use a phosphor on the inner tube surface which emits UV‑A radiation instead of visible light. Some lamps use a deep-bluish-purple Wood's glass optical filter that blocks almost all visible light with wavelengths longer than 400 nanometers. The pur…
