Title: Innovations of John C McCarthy
Introduction
John C McCarthy is a notable inventor based in Stratham, NH (US), recognized for his contributions to advanced laser technology. With a total of 13 patents to his name, McCarthy has made significant strides in the field of laser designators and rangefinders.
Latest Patents
One of his latest patents is the "Dual mode laser target designator/rangefinder with an optical parametric oscillator-optical parametric amplifier (OPO-OPA) converter." This invention focuses on an apparatus and method for a Laser Designator/Rangefinder (LDR) that operates at two wavelengths: 1064 nm and 1572 nm. The 1064 nm wavelength laser is generated by a pump diode exciting the Nd:YAG medium, while the 1572 nm wavelength laser is produced using an OPO-OPA converter located in a bypass path. This innovative design allows for long-range identification and tracking capabilities essential for advanced tactical platforms, all within a compact Size, Weight, and Power Consumption (SWaP) package.
Another significant patent is the "Hybrid resonator and amplifier combination for generating high energy output signal." This invention involves a hybrid resonator and amplifier that generates a high energy output signal. It includes a beam splitter that divides a pump laser beam into two portions. The second portion is directed to a resonator operating in a single transverse mode to generate a signal wavelength beam. An output coupler allows part of the signal wavelength beam to pass while retaining the rest within the resonator. A dichroic mirror directs both portions toward an amplifier, which amplifies the signal wavelength beam to produce a high energy output signal.
