of the femtosecond laser pulse into a chirped white-light laser pulse [9, 10]. Application into long-range atmospheric sensing using the white-light laser pulse has been carried out [11]. One could take advantage of the temporal deformation to compress the pulse into a few energetic cycle pulses [12].

The DX Series offers sufficient pulse energy for selected material processing in a compact form factor. Harmonic generation packages, which convert its output to visible wavelengths, are available. Product Features: Factory-set up to 5 MHz repetition rate available; Air-cooled Femtosecond Lasers for Ophthalmic Surgery Enabled by Chirped-Pulse Amplification Daniel Palanker, Ph.D. This year’s Nobel Prize in Physics was awarded to Donna Strickland (currently at the University of Waterloo, Canada) and Gérard Mourou (now at École Polytechnique in France) for chirped-pulse amplification, an invention that enabled the devel- A femtosecond laser has a pulse duration in the femtosecond range, or one quadrillionth of a second.

The half-wave plate was positioned behind the polarizing plate beam splitter to change the laser polarization direction.

45 ps pulses are amplified to ten’s of watt peak power and propagated through a standard polarization maintaining fiber to reach enough spectral broadening by self-phase-modulation. The double-pulse femtosecond laser was focused with the microscope objective. TiO 2 samples were mounted on a 6-axis miniature hexapod, and the processing process was observed through a charge-coupled device camera.

laser ablation process using ultrashort laser pulses are not still fully understood. Pulse duration of femtosecond laser pulse is shorter than electron-to-ion energy transfer time and heat conduction time in the sample lattice. This results in dif-ferent laser ablation and heat dissipation mechanisms as compared to nanosecond laser ablation. of femtosecond laser pulses with very short pulse-to-pulse intervals (Harzic et al., 2002).

We generated a coherently synthesized optical pulse from two independent mode-locked femtosecond lasers, providing a route to extend the coherent bandwidth available for ultrafast science. The two separate lasers (one centered at 760 nanometers wavelength, the other at 810 nanometers) are tightly synchronized and phase-locked. Coherence between the two lasers is demonstrated via spectral
