Prior art microlaser systems require complex and expensive photovoltaic power sources due to high driving voltage needs, leading to inefficient power consumption and increased costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a photovoltaic power source is used to provide driving voltage to a microlaser, then the microlaser can be operated, but the photovoltaic power source becomes complex and expensive due to high voltage requirements
Solution Approach 1:
The system divides the power source into two independent parts: a simple photovoltaic power source that provides low voltage, and a separate voltage amplifier that boosts the voltage to the required level. This segmentation allows the photovoltaic source to remain simple while still achieving the necessary high driving voltage for the microlaser.
Solution Approach 2:
A voltage amplifier is introduced as an intermediary device between the photovoltaic power source and the microlaser. This mediator takes the low voltage output from the photovoltaic source and amplifies it to the required driving voltage level, enabling the simple photovoltaic source to power the microlaser without requiring complex high-voltage photovoltaic cells.
2Duration of action of stationary object
If a photovoltaic power source provides continuous power to a microlaser, then the microlaser operates continuously, but power consumption increases
Solution Approach 1:
The microlaser operates in periodic pulses rather than continuously. The control system activates the microlaser only when events need to be detected, allowing it to remain off during intervals when detection is not required. This periodic operation significantly reduces average power consumption while maintaining the ability to detect events over extended periods.
Solution Approach 2:
The system uses the microlaser's own emitted light as the trigger signal to activate the voltage amplifier and power the microlaser. When the microlaser emits light indicating an event, this light automatically triggers the power source to activate, creating a self-regulating system that consumes power only when needed for detection.
