A4 Beam Expander Erbium Glass Laser

The Erbium-doped Glass Laser, also known as the 1535nm DPSS Eye-safe Laser, plays a crucial role in various fields, including eye-safe rangefinder modules, laser communication, LIDAR, and environmental sensing.
The laser emits light at a wavelength of 1535nm, which is considered "eye-safe" because it is absorbed by the cornea and crystalline lens of the eye and does not reach the retina, reducing the risk of eye damage or blinding when used in rangefinders and other applications.

WHAT IS ERBIUM-DOPED GLASS LASER?

 An Er:Glass laser is a solid-state laser that uses erbium-doped glass as its active medium, emitting light typically at a wavelength of 1.54 micrometers.

Note

· During transportation, storage, and use, anti-static measures must be taken.

· A short-circuit line should be connected between the laser diode pins for protection.

· Use a constant current power supply, avoiding peaks and surges during operation.

· Do not exceed the specified range of operating temperature, frequency, pulse width, and current as noted in the specifications.

· Ensure reliable installation when the laser is operating.

· The laser window must be kept clean and free of contamination to prevent abnormal light emission.
