Kerr - lens mode - locked femtosecond laser
We have measured the frequency of the 6s S1/2 − 5d D3/2 electricquadrupole transition of Yb with a relative uncertainty of 1 × 10, νY b = 688 358 979 309 312 Hz ± 6 Hz. A femtosecond frequency comb generator was used to phase-coherently link the optical frequency derived from a single trapped ion to a cesium fountain controlled hydrogen maser. This measurement is one of the most accurate measur...
متن کاملKerr - lens mode - locked lasers
The Kerr-lens mode locking ability and the ultrashort pulse characteristics are analyzed numerically for the Cr-doped ZnTe, ZnSe, ZnS active media. The advantages of these materials for the femtosecond lasing within 2-3 µm spectral range are demonstrated.
متن کاملSelf-starting Kerr-lens mode locking of a Ti:sapphire laser.
It is shown that Kerr-lens mode locking of a Ti:sapphire laser, with no intracavity elements except the laser rod and the dispersion-compensating prisms, can be made to be completely self-starting. We achieve this result by carefully designing the resonator to maximize the nonlinear mode variations and dynamic loss modulation.
متن کاملKerr-lens mode-locked visible transitions of a Pr:YLF laser.
We report what is to our knowledge the first Kerr-lens mode locking of the visible transitions at 607 and 639 nm in Pr:YLF. Initiation of the self-mode locking took place through the use of liquid saturable absorbers to establish saturation parameters, and it was carried out in optimized all-solid-state laser configurations (but with gas-laser pumping) with thin s,100-mmd colloidally colored Cd...
متن کاملControllable harmonic mode locking and multiple pulsing in a Ti:sapphire laser.
A new way to control the harmonic mode-locking and multiple pulsing operation with the pulse duration unaffected of a Kerr-lens mode-locked Ti:sapphire laser was demonstrated. When the effective nonlinear length of the nonlinear medium which was inserted in the Ti:sapphire laser was varied by changing the position of the medium or the pump power of the laser, stable harmonic mode-locking and mu...
