Comparison different package of Laser Diode
- TO-Can diode lasers are laser diode packages that are housed in an integrated metal can and have an integrated lens with a threaded mount, making them ideal for use in OEM applications.
- Fiber coupled diode lasers are laser diodes that are coupled to an optical fiber, allowing the laser light to be delivered to a distant location.
- Bar diode lasers are a type of laser diode that consists of multiple laser diodes arranged in a row or bar, allowing the laser light from all the diodes to be combined into a single output beam.
What is TO-CAN Laser Diode package?
TO-Can is a type of packaging used for laser diodes. It is an integrated metal can that houses the diode and has an integrated lens with a threaded mount, making it ideal for use in OEM applications. The packages are hermetically sealed with AR coated windows, providing improved performance and reliability for sensitive encapsulated components.
What is Fiber Coupled Laser Diode Package?
Fiber coupled packages are laser diode packages that use an optical fiber to deliver the laser light from the laser diode to a specific spot. The laser diode is usually coupled to the fiber using an optical connector, such as SNA905 connector.
What is Bar (Array) Laser Diode Package?
Laser diode bars are semiconductor laser devices that are designed to emit a high power light in a single direction. They are usually packaged in a sealed enclosure made of metal or a semiconductor material. The package is designed to dissipate the heat generated by the laser diode bars and protect the device from the environment.Laser diode bars are semiconductor laser devices that are designed to emit a high power light in a single direction.

Fiber Coupled Laser Diode
In a Fiber Coupled packaging, the laser diode is coupled to a fiber optic cable, which delivers the laser beam to the application. This packaging offers excellent beam quality, stability, and flexibility in terms of fiber length and type. It is commonly used in applications such as sensing, telecommunications, and medical devices. However, Fiber Coupled packaging can be more complex and expensive than other packaging options, and it may require additional alignment and coupling components.
