  2. Raman laser - Wikipedia

    en.wikipedia.org/wiki/Raman_laser

    A technique that is commonly employed in these devices is cascading, first proposed in 1994: [5] The "first-order" laser light that is generated from the pump light in a single frequency-shifting step remains trapped in the laser resonator and is pushed to such high power levels that it acts itself as the pump for the generation of "second ...

  3. Resonance Raman spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Resonance_Raman_spectroscopy

    The difference is the choice of the laser wavelength, which must be selected to match the energy of an electronic transition in the sample. A tunable laser is thus often used for resonance Raman spectroscopy, since a single laser can be used to generate many possible excitation wavelengths to match different samples. [8]

  4. Optical parametric amplifier - Wikipedia

    en.wikipedia.org/wiki/Optical_parametric_amplifier

    An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. It is essentially the same as an optical parametric oscillator , but without the optical cavity (i.e., the light beams pass through the apparatus just once or twice, rather than many ...

  5. Ultrafast laser spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Ultrafast_laser_spectroscopy

    A dye laser is a four-level laser that uses an organic dye as the gain medium. Pumped by a laser with a fixed wavelength, due to various dye types you use, different dye lasers can emit beams with different wavelengths. A ring laser design is most often used in a dye laser system.

  6. Nitrogen laser - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_laser

    A nitrogen laser is a gas laser operating in the ultraviolet range [1] (typically 337.1 nm) using molecular nitrogen as its gain medium, pumped by an electrical discharge. The wall-plug efficiency of the nitrogen laser is low, typically 0.1% or less, though nitrogen lasers with efficiency of up to 3% have been reported in the literature.

  7. Regenerative amplification - Wikipedia

    en.wikipedia.org/wiki/Regenerative_amplification

    In laser science, regenerative amplification is a process used to generate short but strong pulses of laser light. It is based on a pulse trapped in a laser resonator, which stays in there until it extracts all of the energy stored in the amplification medium.

  8. Chirped pulse amplification - Wikipedia

    en.wikipedia.org/wiki/Chirped_pulse_amplification

    Chirped pulse amplification (CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level, with the laser pulse being stretched out temporally and spectrally, then amplified, and then compressed again. [1]

  9. Raman amplification - Wikipedia

    en.wikipedia.org/wiki/Raman_amplification

    Raman amplification / ˈ r ɑː m ən / [1] is based on the stimulated Raman scattering (SRS) phenomenon, when a lower frequency 'signal' photon induces the inelastic scattering of a higher-frequency 'pump' photon in an optical medium in the nonlinear regime.
