We present a passive, solid-state threshold-triggered Wideband Protection Filter (WPF) that blocks the transmission only if the power exceeds a certain threshold. We demonstrate the protection ability of the WPF against laser threats including protection behavior for single and series of pulses. The WPF can be readily used for protection of detectors, cameras, or eye safety.
