Exempel på hur du använder LASING i en mening

• Active laser medium (also called gain medium or lasing medium), a quantum system that allows amplification of power (gain) of waves passing through (usually by stimulated emission).
• A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
• The SIL was built primarily to test the COIL at a simulated operational altitude, and during that phase of the program, the laser was operated over 50 times, achieving lasing durations representative of actual operational engagements.
• Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid-state lasing medium.
• Improvements in modulation bandwidth, lasing threshold, relative intensity noise, linewidth enhancement factor and temperature insensitivity have all been observed.
• More recently, Raman lasing has been demonstrated in silicon-based integrated-optical waveguides by Bahram Jalali's group at the University of California in Los Angeles in 2004 (pulsed operation) and by Intel in 2005 (continuous-wave), respectively.
• Some of this light is absorbed by the neodymium atoms in the glass, raising them to an excited state and leading to a population inversion which readies the lasing medium for amplification of a laser beam.
• Peter Sorokin and Mirek Stevenson at IBM's laboratories in Yorktown Heights (US) experimented with this material in the 1960s and achieved lasing at 2.
• Often the mirror's coating is chosen to reflect wavelengths that are shorter than the lasing output while absorbing or transmitting wavelengths that are the same or longer, to minimize thermal lensing.
• Forbidden transitions in rare earth atoms such as erbium and neodymium make them useful as dopants for solid-state lasing media.
• The lasing process involving aluminum garnet crystals is carried out by the dopant atoms, usually rare-earth metals, which take the place of a few atoms of the original metal in the crystal structure (in this case lutetium).
• In 2005, Swager and his team found that adjusting the pump power to just over the required threshold for lasing significantly attenuated the lasing emission, resulting in a thirtyfold increase in the sensitivity of Fido explosives detector sensors when the system is operating near the lasing threshold.
• Later milestones from Snoke and collaborators include showing a clear difference between polariton condensation and standard lasing,.
• On 12 December 1960, Herriott was adjusting the mirrors of the Fabry-Perot structure he had designed, when the group obtained the first spike indicating lasing on the oscilloscope.
• In general, the two regimes of operation are attributed to the scattering properties of the diffusive element in distributed feedback RLs: a weakly (highly) scattering medium, having a transport mean free path much greater than (comparable to) the emission wavelength produce a non-resonant (resonant) random lasing emission.
• In 2006, his group and colleagues at the University of Southampton reported polariton lasing at room-temperature.
• This also means that the response time of spontaneous emission from a gain medium in a nanocavity also decreases, the result being that the laser may reach lasing steady state picoseconds after it starts being pumped.
• The lasing medium in some dye lasers and vibronic solid-state lasers produces optical gain over a wide bandwidth, making a laser possible which can thus generate pulses of light as short as a few femtoseconds.
• Nonlinearities can result in both spatial and temporal harmonics in the near field at the nucleus, opening the range of possibilities for rapid transfer from the storage state to the upper lasing state using other kinds of triads involving transition energies at multiples of the optical laser quantum energy and at higher multipolarities.
• The nonequilibrium superradiant transition and the lasing instability have several similarities and differences.
