In the absence of alive stabilization, the alliteration amount and carrier-envelope account abundance would be chargeless to drift. They alter with changes in the atrium length, refractive basis of laser optics, and nonlinear furnishings such as the Kerr effect. The alliteration amount can be counterbalanced application a piezoelectric transducer, which moves a mirror to change the atrium length.
In Ti:sapphire lasers application prisms for burning control, the carrier-envelope account abundance can be controlled by angry the top reflector mirror at the end of the prism pair. This can be done application piezoelectric transducers.
In top alliteration amount Ti:sapphire ring lasers, which generally use double-chirped mirrors to ascendancy dispersion, accentuation of the pump ability application an acousto-optic modulator is generally acclimated to ascendancy the account frequency. The appearance blooper depends acerb on the Kerr effect, and by alteration the pump ability one changes the aiguille acuteness of the laser beating and appropriately the admeasurement of the Kerr appearance shift. This about-face is far abate than 6 rad, so an added accessory for base acclimation is needed. See also: phase-locked loop
The advance which led to a applied abundance adjust was the development of technology for stabilizing the carrier-envelope account frequency.
