Definition of lase in English:



  • (of a substance, especially a gas or crystal) undergo the physical processes employed in a laser; function as or in a laser.

    • ‘After lasing, there was no statistically significant reduction in overall yield stress, ultimate stress, or elastic modulus when comparing the lased and the nonlased tissue.’
    • ‘‘There have been many attempts, but no one had been able to get silicon to lase before now,’ notes Bahram Jalali, the physicist who led the U.C.L.A. team.’
    • ‘The primary laser beam is generated by a megawatt chemical oxygen iodine laser located at the rear of the fuselage, which lases at 1.315 micron wavelength.’
    • ‘Furthermore, QD devices have lased at 1.3 m, a necessary attribute for access network communication systems that use GaAs substrates.’
    • ‘These points of light do not exhibit coherent properties commonly associated with laser light, although peers agree that the ‘random laser’ does indeed lase.’
    • ‘Unlike QW lasers, which have a continual energy spectrum, QD structures have an energy gap between the lowest state that lases and the next state.’
    • ‘They are polar compounds and exhibit a high fluorescence quantum yield and lase efficiently both in liquid and in solid solutions, with some of them outperforming the laser performance of the reference dye Rhodamine 6G.’
    • ‘The source of heat in the laser material is the absorption of intense diode-laser pump light, which is used to excite a particular transition and produce the population inversion necessary for lasing.’
    • ‘Nanopowders can lase or can upconvert light, finding potential applications such as security and anticounterfeiting.’
    • ‘Many organic molecules and polymers have been observed to lase in the visible spectrum from the red to the blue, but success has been elusive at the deep blue wavelengths.’
