Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single laser oscillator is used for both detection and dealing, then the device structure is simple, but the detection efficiency and dealing precision are reduced
Solution Approach 1:
The patent divides the laser oscillator into two separate groups: a first laser oscillator group dedicated to emitting detection laser light for target acquisition and tracking, and a second laser oscillator group dedicated to emitting dealing laser light for target destruction. This segmentation allows each group to be optimized for its specific function, improving both detection efficiency and dealing precision while maintaining overall system coordination through the controller.
2Speed
If mechanical methods are used to change laser irradiation direction, then the control is simple, but the response speed is slow and the system is complex
Solution Approach 1:
The patent replaces mechanical direction-changing methods with an optical approach. Each laser oscillator is equipped with a polarization controller and a wavelength controller that can non-mechanically adjust the emission direction of laser light by modifying the polarization state and wavelength. This substitution achieves rapid direction changes without mechanical moving parts, thereby improving response speed while reducing mechanical complexity.
3Power
If high-power continuous wave laser light is used to destroy target, then the destruction capability is strong, but the detection precision and response time are reduced
Solution Approach 1:
The patent segments the laser system into two distinct power levels: the first laser oscillator group emits lower-power continuous wave laser light optimized for precise target detection and tracking, while the second laser oscillator group emits high-power pulsed laser light optimized for target destruction. This segmentation allows the system to maintain high detection precision during the detection phase and delivers maximum destruction power during the dealing phase, resolving the contradiction between detection precision and destruction capability.
4Device complexity
If laser beam direction is changed by wavelength, then the mechanical structure is simplified, but the energy loss increases
Solution Approach 1:
The patent employs precise control of laser parameters (polarization state and wavelength) to adjust beam direction. By using polarization controllers and wavelength controllers, the system can redirect laser beams without mechanical movement or additional optical components that would cause energy loss. This parameter-based control method maintains high energy efficiency while achieving flexible direction changing, resolving the contradiction between mechanical simplification and energy conservation.

Function Achieved in This Case
The apparatus enables efficient detection and destruction of targets by overlaying laser beams to concentrate energy effectively, allowing for precise targeting and handling multiple targets or moving objects.
Implementation Method 1
Incident light, that incidents in the incident port provided at an end in the first direction of the first VCSEL, travels inside the first VCSEL along the first direction, while being reflected in a vertical direction, and is emitted from the emitting port on an upper surface of the first VCSEL as emission light

AI summary
A laser irradiation apparatus that efficiently carries out processes such as target detection. The laser irradiation apparatus (1) is provided with a laser array (10), a detector (20) and a controller (30). The laser array is provided with a plurality of laser oscillators including a first laser oscillator (11) that irradiates first detection laser light and a second laser oscillator (11) that irradiates second dealing laser light. The detector obtains detection information based on reflected light (503) that is the first detection laser light reflected by a target (2). The controller estimates a position of the target based on the detection information and generates a second dealing signal that instructs to irradiate the second dealing laser light to the estimated position of the target. The second laser oscillator irradiates dealing laser light to the estimated position of the target based on the second dealing signal.
