Greater than 1W power can be reached when the frequency doubling is resonator enhanced, resulting in Watt-class sources spanning across the visible spectrum, including a 400 nm blue laser with 2.6 W of output power. [23] Violet DPSS laser pointers (120 mW at 405 nm) use a direct diode infrared gallium arsenide (1 W @ 808 nm) lasers being ...
Holmium YAG (Ho:YAG) laser 2.1 μm Flashlamp, laser diode Tissue ablation, kidney stone removal, dentistry. Chromium ZnSe (Cr:ZnSe) laser 2.2 - 2.8 μm Other laser (Tm fiber) MWIR laser radar, countermeasure against heat-seeking missiles etc. Cerium-doped lithium strontium (or calcium) aluminum fluoride (Ce:LiSAF, Ce:LiCAF) ~280 to 316 nm
4000 watt CO 2 laser cutter. There are three main types of lasers used in laser cutting. The CO 2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in the application. Nd is used for boring and where high energy but low repetition are required.
This is due to the shorter wavelength (405 nm) of the blue-violet laser employed. MOs use a 650 nm-wavelength red laser. MOs use a 650 nm-wavelength red laser. Because its beam width is shorter when burning to a disc than a red-laser for MO, a blue-violet laser allows more information to be stored digitally in the same amount of space.
This emission is in the thermal infrared at 10.6 μm; such lasers are regularly used in industry for cutting and welding. The efficiency of a CO 2 laser is unusually high: over 30%. [64] Argon-ion lasers can operate at several lasing transitions between 351 and 528.7 nm. Depending on the optical design one or more of these transitions can be ...
Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Excimer laser was proposed in 1960 by Fritz Houtermans. [1] The excimer laser development started with the observation of a nascent spectral line narrowing at 176 nm reported in 1971 [2] by Nikolai Basov, V. A. Danilychev and Yu. M. Popov, at the Lebedev Physical Institute in Moscow, using liquid xenon dimer (Xe 2) excited by an electron beam.
EUV (10–121 nm) is the band longer than X-rays (0.1–10 nm) and shorter than the hydrogen Lyman-alpha line. While state-of-the-art 193 nm ArF excimer lasers offer intensities of 200 W/cm 2 , [ 62 ] lasers for producing EUV-generating plasmas need to be much more intense, on the order of 10 11 W/cm 2 .
