Latest Patents

One of Ragle's latest patents is the Bulk Avalanche Semiconductor Laser. This invention utilizes optically triggered avalanche conduction to initiate lasing action in a bulk semiconductor. The design features a semiconductor block with electrodes on opposing sides, where a high voltage is applied that is less than the voltage required for avalanche breakdown. When irradiated with light, charge carriers are produced, leading to avalanche conduction and resulting in laser emission.

Another notable patent is the Bulk Avalanche Semiconductor Switch Using a Mesa Structure. This switch employs an improved method of optically-triggered avalanche breakdown, capable of producing pulses of 100 picoseconds or longer. It can deliver five kilovolts into 50 ohms using a standard laser diode. The design includes a semiconductor block with contacts on opposing sides, where a high voltage is applied. The mesa structure allows for field compression, generating an avalanche breakdown field across the semiconductor block.
