laser diode的用法和樣例：
例句
- The light is emitted by the laser diode and enters a diffraction grating.
激光束從激光二極體中發出，射入衍射光柵。 - Different models should be suitably chosen to simulate the far-field behavior in the fast and slow axes of heterostructure laser diode at different power levels.
在不同功率水平下，異質結激光二極體快軸與慢軸方向的遠場行為應選用不同的模型模擬。
