    FIGURE 1. Mechanisms for laser-induced damage differ significantly across pulse duration timescales. Longer pulses, including those with nanosecond durations, cause damage primarily through thermal effects. As pulse durations shrink to femtosecond timescales, carrier absorption and nonlinear effects become the dominant mechanisms.[2]
    Understanding laser damage mechanism differences between femtosecond and nanosecond lasers promotes efficiency and longevity of laser systems.

    FIGURE 1. The chromaticity area for measured and reference color gamuts, and the relative chromaticity areas and CIELab color gamut volumes for each gamut.
    Using a chromaticity plot to describe color capability is a relic of cathode-ray tube (CRT) displays and no longer valid. The Gamut Ring plot is the new standard and should always...
