Latest Patents

William A. Bell's most recent patent is titled "Active Q-switched high power single mode laser." This invention describes a high power single mode laser that incorporates a Q-switch for switching the laser on in two stages. Initially, the laser operates at a relatively high loss level just above the threshold, allowing a train of relaxation oscillator spikes to be established. Subsequently, the Q-switch transitions to a lossless state, enabling the resonant mode within the laser to build up to maximum power. An optical detector monitors the resonant optical radiation level and produces an output signal for each relaxation spike. The trigger circuit, responsive to these detected spikes, enhances the single longitudinal mode operation of the laser. Additionally, quarter wave plates are strategically placed within the optical resonator to ensure a more uniform power density distribution within the laser gain medium.
