Abstract: The current disclosure is directed to an apparatus and method of a Laser Designator/Rangefinder (LDR) having two wavelengths of 1064 nm and 1572 nm. The 1064 nm wavelength laser is generated by a pump diode by exciting Nd:YAG medium (source). The 1572 nm wavelength laser is produced using an OPO-OPA converted which is located in a by-pass path. Because the 1572 nm wavelength uses near diffraction limited signal, it provides long range identification and tracking capability needed for advanced tactical platforms, while using the smallest transmit aperture, in a low Size, Weight and Power Consumption (SWaP) package.

Abstract: A hybrid resonator and amplifier combination for generating a high energy output signal. The combination comprises a beam splitter for splitting a pump laser beam into first and second portions. The second portion beam being conveyed to a resonator which operates in a single transverse mode to generating a signal wavelength beam. An output coupler of the resonator allows a first portion of the signal wavelength beam to pass therethrough while retaining a second portion of the signal wavelength beam within the resonator. A system dichroic mirror receives and directs both the first portion and the signal wavelength beam toward an amplifier. The amplifier receives both the first portion and the signal wavelength beam. The first portion, upon passing through the amplifier, creates gain which is used by the amplifier to amplify the signal wavelength beam generate the high energy output signal.
