In our first blog, we covered how to design with Acousto-Optic (AO) Q-Switches. Now, let's dive into a critical performance metric: switching speed. When you're trying to generate a clean, short pulse, how quickly you can transition from a high-loss to a low-loss state is paramount. This speed is defined by two related but distinct concepts: Rise Time and Switching Time. Understanding the difference—and what limits them—is key to pushing your laser's performance.
