Latest Patents

One of Lacour's latest patents is a "Capacitor discharge excited gas laser." This invention features a gas-filled channel that extends between a pair of metal plates. The laser is excited by a spark discharge through the gas from one plate to the other. The energy for the spark is derived from built-in capacitors located between the plates on either side of the channel. Notably, the capacitor dielectric is water, which is pumped around a cooling circuit. This design ensures that the water is not permanently damaged in the event of an accidental discharge. The invention is particularly applicable to nitrogen and excimer lasers.

Another significant patent is for a "Gas laser in which the gas is excited by capacitor discharge." This gas laser includes two capacitors formed by parallel metal plates, with dielectric parts spaced apart to create a passage containing the laser gas. It also features a transformer connected to the plates, which is essential for the operation of the laser. This invention is particularly useful for exciting gas lasers that contain dye stuff.
