Study of laser ablation using nano-second laser pulses

 In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...

Temporal smoothing of multimode dye-laser pulses.

Pulses from a broadband dye laser operating in many modes have been temporally smoothed by passing them through a strongly saturated dye amplifier in the presence of a strong, nonsaturable absorber. The standard nonlinear coupled partial differential equations based on the rate-equation approximation have been used to model the amplifier. Both analytic and numerical solutions for the equations ...

Temporal decorrelation of short laser pulses

We describe a unique approach for extracting the temporal profile of ultrashort laser pulses from typical autocorrelation measurements. The use of the constraint that intensity is a nonnegative quantity enables an iterative numerical algorithm to reconstruct pulse shapes in a one-dimensional procedure. With the reconstruction of the intensity profile, the Gerchberg–Saxton algorithm can be used ...

The Measurement of Ultrashort Laser Pulses

Indeed, to see the action in any fast event, whether it’s a computer chip switching states, dynamite exploding, or a simple soap bubble popping, requires a strobe light with a shorter duration in order to freeze the action. But then to measure the strobe-light pulse requires a light sensor whose response time is even faster. And then to measure the light-sensor response time requires an even sh...
