What is a Laser Module?

A laser module is a combination ofa laser diode(LD)、optical components、mechanical componentsandelectronic components.

　　⪧Optical components: Devices such as lenses, mirrors, or beam shapers that help control, focus, generate, and emit laser beams.
　　⪧Mechanism components: Hold LDs, optics and electronics in place.
　　⪧Electronic components: Drive the LD to produce a constant light energy output. In appearance, the laser module looks like a complete device, while the LD is more like a small electronic component.

Advantages of SMD packaging

Part bonding technology continues to develop into smaller and lighter surface mount components (SMD), and special-shaped molds and semiconductor packages are becoming more and more diverse. Now it is the most important packaging method in modern electronic manufacturing industry. SMD is thin and light in size and consumes low cost and man-hours. The Zener Diode plays an important role in protecting LD in SMD.

Advantages of TO packaging

The transistor package (TO package) is composed of a metal shell and pins. Metal helps to dissipate heat. Its characteristics and dimensions vary according to different manufacturers and models, so the device type and performance requirements need to be considered when selecting. TO packaging is very practical in high power and high temperature applications because of its good heat dissipation performance and metal protection.
