Laser diodes, modules, and applications are a growing technology in the scientific, technological, and medical industries. The VLM-635-04 linear polarization alleviating module (LPA) is one such product that optimizes the polarization of laser radiation while preserving the pointing direction. This article will discuss the application field and working principle of the VLM-635-04 LPA.

The fields of application for the VLM-635-04 LPA include telecommunications, such as fiber-optic communications, and indoor positioning. The VLM-635-04 is a small form factor, lightweight, and low cost product that optimizes the polarization of laser radiation while preserving the pointing direction. This makes it suitable for many different applications where a stable, low loss operation is desired.

The working principle of the VLM-635-04 LPA is based on the Faraday effect. This effect is used to rotate the plane of polarization of laser radiation through an angle of 45 degrees. The LPA is based on a Faraday rotator, which is a device made of a birefringent material, such as quartz, through which the light is passed and whose polarization plane is rotated according to the Faraday effect. The LPA also includes a correction lens set, which allows the user to adjust the plane of polarization of the output light, thus providing an adjustable output power.

The VLM-635-04 LPA is a reliable and cost-efficient product that optimizes the polarization of laser radiation while preserving the pointing direction. It is used in a variety of applications, such as fiber-optic communications, indoor positioning, and more, making it a versatile and powerful tool for many applications. Its operation is based on the Faraday effect, which is used to rotate the plane of polarization of laser radiation, and its correction lens set allows for adjustable output power. The VLM-635-04 LPA is an ideal product for optimizing the polarization of laser radiation.
