About Laser Diodes (LD)
What is a Laser Diode (Semiconductor Laser)?
A Laser Diode (LD) is a device that generates laser light by sending electricity through a circuit element made of semiconductor material. It is also called a “Semiconductor Laser.”
What is the difference between a Laser Diode and an LED (Light Emitting Diode)?
Laser diodes have a narrow light spectrum and high directionality (a straight path). In contrast, LEDs have low directionality and diffuse illumination. These distinctions support different design objectives, and both light sources are used in a wide range of applications.
Laser Diode Lifespan
The lifespan of a laser diode is determined to a large degree by its operating environment. Exposure to high temperatures shortens the life of the laser IC, and since the IC itself generates heat during laser oscillation, thermal management is essential to a laser diode’s performance and longevity. Ceramics with high thermal conductivity can efficiently dissipate heat. Kyocera offers high heat dissipation materials and can propose ceramic package and sub-mount solutions based on customer requirements.
