Liquid-crystal lasers are comparable in size to diode lasers, but provide the continuous wide spectrum tunability of dye lasers while maintaining a large coherence area. The tuning range is typically several tens of nanometers. [1] Self-organization at micrometer scales reduces manufacturing complexity compared to using layered photonic ...
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).
Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient single-transverse mode, and single-longitudinal-mode, emission with laser linewidths as narrow as 350 MHz (approximately 0.0004 nm at a wavelength of 590 nm), in the high-power pulsed regime.
However, by 1990, the interest in chemical lasers had shifted toward shorter wavelengths, and the chemical oxygen iodine laser (COIL) gained the most interest, producing radiation at 1.315 μm. There is a further advantage that the COIL laser generally produces single wavelength radiation, which is very helpful for forming a very well focused beam.
Remote laser spectroscopy uses laser ablation to create a plasma from the surface material; the composition of the surface can be determined by analyzing the wavelengths of light emitted by the plasma. Laser ablation is also used to create pattern, removing selectively coating from dichroic filter. This products are used in stage lighting for ...
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 .
A chemical oxygen iodine laser (COIL) is a near–infrared chemical laser. As the beam is infrared, it cannot be seen with the naked eye. It is capable of output power scaling up to megawatts in continuous mode. [citation needed] Its output wavelength is 1315 nm, a transition wavelength of atomic iodine.
Amazin' Lazer — A consumer grade laser gun used for cleaning up yard waste or (as onscreen superimpositions discourage) dangerous and potentially criminal acts. [21] The Amazing Alexander – This 1986 ad promotes a Broadway theatre performance by a popular stage hypnotist (portrayed in performance still shots by Jon Lovitz). Audience members ...
