Тезаурус:
- Because either or both of these can be varied over wide limits, FELs are broadband tunable lasers.
- Editor , - M J C Van Gemert and colleagues echo the opinion of most of those who use laser treatment for port wine stain malformations that pulsed tunable dye lasers with a wavelength of 577 or 585 nm are the best choice for treating children.
- Working with Kung, they used a wavelength-tunable dye laser to illuminate jets of argon, generating a third harmonic output tunable continuously between 97.3 and 102-;3 nanometres .
- The spectrum was recorded using a tunable IR diode laser.
- FELs are now a mature technology, and are competing with conventional lasers as tunable light sources.
- The use of a tunable laser may be helpful, as excitation profiles, which show the intensity of resonance-enhancement as a function of exciting frequency, may allow overlapping electronic bands to be distinguished from each other.
- In the infrared there are two wavelengths, at 3 and 6 , with extremely high water absorption, coupled with good transmission through fibre optics, and FELs open up the possibility of using a tunable laser operating in a pulsed mode in these regions, thus minimising tissue damage.
- In RFS a parallel beam of light at a single frequency (or energy) from a tunable laser is directed at the atoms.
- Such research has become possible only with the advent of tunable lasers, which can emit light over a range of wavelengths.
- The production of the CH 3 radical by flash photolysis of CH 3 I, for instance, has been monitored using a tunable IR laser set at a fixed frequency of 608.301 cm -1 , coinciding with the strong Q-branch of the 2 band.
- Unfortunately a monochromatic beam is of only limited use for spectroscopy unless it is tunable.
- A third type of spectrometer, fundamentally simpler than the other two, uses a tunable monochromatic source; instruments using IR-emitting diodes have been produced, but are not yet able to replace interferometers.
- In recent years, however, the introduction of tunable lasers as excitation sources has allowed laser-induced fluorescence spectra to be obtained.
