Kerr-lens mode-locked Ti:sapphire laser with an additional intracavity nonlinear medium.

چکیده
We demonstrate a Kerr-lens mode-locked Ti:sapphire laser with an additional Yb(3+) doped Potassium Yttrium Tungstate crystal (Yb:KYW) in the laser cavity, where not only the pump threshold to start mode-locking but also the stable regions to maintain mode-locking can be well-controlled by varying the position of Yb:KYW nearby the confocal focus to change the intracavity Kerr-effects. The pump threshold is reduced down to 800 mW to start the mode-locking operation, which is about 27% less than that for a Ti:sapphire laser without an additional Yb:KYW.

Kerr lens mode locking without nonlinear astigmatism
We demonstrate a Kerr lens mode-locked folded cavity using a planar (non-Brewster) Ti:sapphire crystal as a gain and Kerr medium, thus cancelling the nonlinear astigmatism caused by a Brewster cut Kerr medium. Our method uses a novel cavity folding in which the intracavity laser beam propagates in two perpendicular planes, such that the astigmatism of one mirror is compensated by the other mirr...
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...
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 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 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 ...
