Laser diodes and modules play a key role in modern society, with applications ranging from communications, medical, industrial, military, and scientific studies. The well-known VLM-850-01 is a popular laser diode module renowned for its reliable and efficient performance. This article will explore the application field and working principle of this module.The VLM-850-01 diode module uses a single vertical cavity laser diode array (VCSEL) with vertical current injection, which offers many advantages such as high on/off contrast, wide emitting angle, and low threshold. This module packs a maximum output power of up to 2.0W, at a wavelength of 850nm. The emission area of the module is very small, and it has a beam divergence of less than 20°. The high power and wide range of applications makes this laser diode the perfect choice for applications such as metrology, optical sensing, defence, medical diagnostics, and research.The module is also highly resistant to the environment, which is a big plus for applications in harsh environments. The power supply voltage of the module is adjustable, and it can easily be adjusted to fit the needs of different applications. It also supports a wide range of working currents, ranging from 0.3A to 15A.The working principle of the VLM-850-01 diode module is based on the VCSEL technology. The VCSEL diode has a vertical cavity structure where the beam is perpendicular to the active surface and parallel to the diode substrate. This structure provides excellent optical properties such as brightness, efficiency, and low divergence.The VCSEL operates in a continuous wave (CW), pulse mode or quasi-CW mode. In the p-i-n structure, the beam is generated from the element of the vertical active surface. The current injection is controlled by applying a static voltage across the substrate. When the current reaches the threshold, the carrier is injected to the p-region and the transverse optical field is generated. This process is repeated to quickly produce a continuous high-power stable laser beam.The VLM-850-01 diode module is an extremely reliable and efficient laser diode that is suitable for a variety of applications. Its vertical cavity structure and excellent optical properties make it ideal for applications that require high power and precision. It is also easily deployable in harsh environments and can be adjusted to fit the needs of various applications. As such, the VLM-850-01 laser diode module is a well-known and popular choice for many applications.
