... where tp is the pulse duration and ∆ν is the full width at half maximum. Nonlinear processes in the components of the resonator due to the high peak intensities of the laser pulses or insufficient modulation depth of the AOM such as dispersion can lead to deviations from this ideal value. For mode-l ...

Laser Cutting
... Of course this was all theoretical, it was not until the 1950s that the detail of how to go about light amplification were finally worked out. It would be the 1960s before the first laser oscillatiors were actually constructed. These devices could emit an intense beam of light made up of photons whi ...
