摘要： A thermal management system for a directed energy weapon includes a first heat exchanger thermally coupled to the directed energy weapon and a second heat exchanger arranged in fluid communication with the first heat exchanger to form a closed loop. The second heat exchanger is thermally coupled to a secondary system and a thermal management fluid circulates within the closed loop. A thermal storage device is arranged in fluid communication with the first heat exchanger and the second heat exchanger. The thermal storage device contains a material and a mode of operation of the directed energy weapon is dependent on a condition of the material in the thermal storage device.

摘要： A method of controlling a semiconductor element that includes a semiconductor laser diode (LD), a semiconductor modulator, and a semiconductor optical amplifier (SOA) is disclosed. The LD generates CW light supplied with the first bias current. The semiconductor modulator generates a modulated light by modulating the CW light supplied with a driving signal. The SOA generates an optical signal by amplifying the modulated light supplied with the second bias current. The method first sets the second bias current in a region where the output power of the optical signal shows negative dependence of the second bias current. Then, a temperature of the semiconductor element, the first bias current, and the driving signal are adjusted such that the optical signal shows performance in respective preset ranges.

摘要： Methods and related modular laser systems, e.g., distributed aperture, ultra short pulsed laser, are provided on a host platform having multiple compartments and groups of components where each group has a different environmental sensitivity such as temperature, humidity, vibration, etc or other installation constraints. Each component group is placed in different compartments of the host platform based on constraints comprising equipment, size, available installation footprint, equipment interconnection, and location constraints. For example, one group with one temperature sensitivity falling within environments provided for aircraft passengers or crews can be placed in the crew or passenger compartments. Other components having a greater temperature tolerance might be placed in an equipment bay having a different temperature range than a crew/passenger cabin. Other components might be placed in an area without any environmental controls or even pressurization (e.g., a cargo bay). Components can be located based on single, multiple, or combinations of constraints.

摘要： A laser oscillator according to this invention includes a resonator unit, heat exchangers, fans, a resonator temperature measuring unit, and a fan control unit. The resonator unit resonates a laser beam to be output. The heat exchangers are arranged adjacent to the resonator unit and are to be supplied with a cooling liquid. The fans are arranged at least at one of two opposite positions across both the resonator unit and the heat exchangers and generate airflow in one direction, which passes through both the resonator unit and the heat exchangers. The resonator temperature measuring unit measures the temperature of the resonator unit. The fan control unit controls the fans. The fan control unit switches the direction in which air is blown by the fans, based on the temperature of the resonator unit.
