| | Sponsored | | Laser specifications change over time. They are also affected by the surrounding environmental conditions and the optical components that guide the beam to its delivery point. It is therefore necessary to validate laser parameters accurately and frequently in research projects. Learn about laser output measurement and the numerous benefits it can bring to your defense organization. |

![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]](https://img.laserfocusworld.com/files/base/ebm/lfw/image/2024/07/66aa8a8410ae71b5de963fc2-2409lfw_whe_1.png?auto=format&fit=fill&fill=solid&w=650&h=361&cache=0.2066748168549326)
