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 کاملCharacteristics of a femtosecond transform-limited Kerr-lens mode-locked dye laser.
Using an SF6 glass plate as the intracavity Kerr medium and a double-prism pair for dispersion compensation, we developed a femtosecond transform-limited passively mode-locked dye laser. Self-starting mode locking is achieved with a dilute intracavity TCVEBI saturable-absorber jet. Within a 50% power drop the tuning range is 577-606 nm. Pulse characteristics of the laser agree with theoretical ...
متن کاملCompletely self-starting picosecond and femtosecond Kerr-lens mode-locked Ti:sapphire laser
Completely self-starting and stable operation of a Kerr-lens mode-locked Ti:sapphire laser was realized in both picosecond and femtosecond regimes. The cavity has a symmetric X configuration with soft aperturing. Enhanced Kerr nonlinearity and reduced backscattering effects were thought to be key to obtaining stable self-starting self-mode-locked operation from 765 to 815 nm for the picosecond ...
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...
