** Intense pulsed light ( high-energy lamps )

Intense pulsed light, commonly abbreviated as IPL, is a technology used by beauty studios and medical practitioners to perform various skin treatments including hair removal and photorejuvenation.

Intense pulsed light, a registered trademark, describes the use of intense pulses of non-coherent light distributed over a range of wavelengths from 500nm to 1200nm, for removal of hair and other purposes.

Intense heating will cause denaturation and coagulation of cellular proteins, rapidly killing cells within a tumour.

Intense attacks against U. S. and Western interests, including two truck bombings of the US Embassy in 1983 and 1984 and the landmark attacks on the U. S. Marine and French parachute regiment barracks on October 23, 1983, led to an American withdrawal, while the virtual collapse of the Lebanese Army in February 1984 was a major blow to the government.

Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known.

Intense tornado activity in the United States.

Intense tornadoes have been observed forming simultaneously with a mesocyclone aloft ( rather than succeeding mesocyclogenesis ) and some intense tornadoes have occurred without a mid-level mesocyclone.

Intense as were his Christian convictions, he could sanction nothing that would do deliberate violence to the convictions of another ; and he had a faith that Christian truth would eventually prevail on its own merits, and need never fear to be set side by side with the truths that other religious systems contain.

Intense, targeted fisheries for manta rays have long-term detrimental effects, due to the low reproductive rates and long lifespans of mantas.

Intense heat focused on a small spot can be used to cut through metal or weld metal components together both by melting metal from the components, and by injecting molten metal from the thermite reaction itself.

Intense neuronal IL-2 immunoreactivity in brainstems of SIDS victims was found, which could be responsible for decreased cardiorespiratory and arousal responses.

Intense opposition from factions of the PDPA was sparked by the repression imposed on them by Daoud's regime and the death of a leading PDPA member, Mir Akbar Khyber.

Intense debate ensued in the late 1960s, after a number of hybrid cyclones formed in the Atlantic Basin.

Intense Congressional review during 1975-76 created turbulence within the national Intelligence Community.

A laser can be classified as operating in either continuous or pulsed mode, depending on whether the power output is essentially continuous over time or whether its output takes the form of pulses of light on one or another time scale.

This nonlinearity is typically only observed at very high light intensities ( values of the electric field comparable to interatomic electric fields, typically 10 < sup > 8 </ sup > V / m ) such as those provided by pulsed lasers.

There are several methods for measuring the temporal coherence of the light ( see: field-autocorrelation ), including the continuous wave Michelson or Fourier transform spectrometer and the pulsed Fourier transform spectrograph ( which is more sensitive and has a much shorter sampling time than conventional spectroscopic techniques, but is only applicable in a laboratory environment ).

Since lasers and intense pulsed light sources cause thermal damage to the skin, there are concerns that laser or intense pulsed light treatments for acne will induce hyperpigmented macules ( spots ) or cause long-term dryness of the skin.

Methods include waxing, sugaring, epilation devices, lasers, threading, intense pulsed light or electrology.

Laser range gated imaging is another form of active night vision which utilizes a high powered pulsed light source for illumination and imaging.

One cause of confusion is the range of names used for intense pulsed light treatments, as intense pulsed light is a registered trademark, which was strongly policed during the early days of the technology, hence the introduction of new names and trademarks for similar or identical treatments .. IPL and equivalent treatments are referred to as VPL, SPL, SPFT, SPTF, SIPL, PTF, CPL, AFT, E-Light, ELOS, M-Light, and other names.

For pulsed ( amplitude modulated ) light, it is said to measure the phase between the carriers.

Certain species of carbon nanotubes also undergo photochemical reactions when exposed to intense pulsed light from a laser, arc lamp, or flashbulb.

Such devices are frequently used for speed limit enforcement, although more modern LIDAR speed gun instruments, which use pulsed laser light instead of radar, have begun to replace radar guns in the past decade, because of limitations associated with small radar systems.

Since cw lasers often have free-running linewidths in the MHz range, and pulsed even larger, it is non-trivial to couple laser light effectively into a high finesse cavity.

In a typical experiment, both the light for excitation (' pump ') and the light for measuring the absorbance (' probe ') are generated by a pulsed laser.
