lasing medium造句

• Semiconductor ring lasers are literally ring-shaped optical waveguides with a lasing medium.
• An FP laser will lase at multiple cavity modes within the gain bandwidth of the lasing medium.
• :A classical example of a negative temperature system is a lasing medium in an inverted state.
• His successful design utilized synthetic pink ruby crystal as the lasing medium and a helical xenon flash lamp as the excitation source.
• Since the lasing medium was fairly small, a single bomb could host a number of them and attack multiple ICBMs in a single burst.
• Titanium-sapphire refers to the lasing medium, a crystal of sapphire ( Al 2 O 3 ) that is doped with titanium ions.
• While attending a conference in 1959, Maiman listened to a speech given by Schawlow, describing the use of ruby as a lasing medium.
• The low pressure and fast flow make removal of heat from the lasing medium easy, in comparison with high-power solid-state lasers.
• In a " colliding-pulse mode-locked laser " the absorber steepens the leading edge while the lasing medium steepens the trailing edge of the pulse.
• Because of high gain in the lasing medium, short upper-state lifetimes ( 1 & ndash; 100 Doppler broadened, which depends on the ions'temperature.
• This doesn't couple the light as well into the lasing medium, since the light makes many reflections before reaching the rod, but often requires less maintenance than metalized reflectors.
• 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.
• 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.
• To keep the required implosion speed, they request that the NIF energy be increased to 2MJ . One must also keep in mind that neodymium lasers can withstand only a limited amount of energy or risk permanent damage to the optical quality of the lasing medium.
• 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 ( 10  " 15 s ).
• Saturated operation meant that the maximum possible power was extracted from the lasing medium, resulting in the high peak energy of 0.3 mJ . The active medium was samarium plasma produced by irradiating samarium-coated glass with a pulsed infrared Nd-glass laser ( wavelength ~ 1.05 祄 ).
• I think that if it is " true " then there should be many other ways to get to the same end of making the effect macroscopic-for example, I think you might have what begins as a single photon pass through a long series of tunneling barriers, while being in a lasing medium to increase its intensity ( to make up for reflection losses in tunneling ) . talk ) 18 : 21, 7 January 2013 ( UTC)
