Actively Q-switching technique has a precise sequential control by external triggering while the high hold-off ability is beneficial to energy storage and high energy output [11], [12], [13]. Electro-optical Q-switching has been widely employed in nanosecond pulsed lasers [14], [15], [16] .

Soft photonic crystals are appealing due to their self-assembly ability, wide tunability, and multistimuli-responsiveness. However, their response time is relatively slow, ranging from milliseconds to minutes.

8.1.1 Fundamental Principle of Active Q-SwitchingThe method of active Q-switching relies on the following considerations (see Fig. 8.1).We assume a pump pulse with a length of approximately (100,upmu ) s (e.g., from a flashlamp) with a sufficiently high energy to generate a large inversion while the laser resonator is blocked and no
