Application Field

The NV4V41SF-A offers a wide range of applications including spectroscopy, barcode reading, laser pointers, and visible light communication.1. Spectroscopy: The NV4V41SF-A enables the use of lasers for spectroscopy applications, such as laser-induced fluorescence (LIF). It is well suited for applications that require a narrow linewidth and high stability.2. Barcode reading: barcodes are used in many areas of life, such as POS systems in stores, libraries and airports. The NV4V41SF-A can be used in barcode readers, which require a high power, and fast response.3. Laser pointers: laser pointers are used in seminars and classrooms to demonstrate materials and illuminate points on a projector screen. The NV4V41SF-A offers a high-power, ultra-small package, making it ideal for these applications.4. Visible light communication: The NV4V41SF-A can be used in visible light communication applications, which includes wireless transmission of data and control signals via the visible light spectrum.

Working principle

The NV4V41SF-A is a high-power, visible laser diode module based on optically-pumped semiconductor (OPC) laser diode technology. This technology takes advantage of the principles of stimulated emission, which is generally referred to as laser action. This module generates laser radiation from a diode with a high energy efficiency.The NV4V41SF-A uses a semiconductor laser diode with two junctions. A high voltage applied between the two junctions results in the injection of electrons across the junctions and into the active region. The injected electrons and holes form a recombination area, where they combine and release photons in the form of laser radiation. This recombination is known as stimulated emission, and is the driving force behind the laser action.The NV4V41SF-A also uses a mirror cavity, which consists of two mirrors, one of which is partially reflective. The laser radiation generated by the diode is bounced between the mirrors, as the partially reflective mirror allows some of the laser radiation to escape. This partially reflected laser radiation creates a beam of visible light, which is the collimated laser emission from the NV4V41SF-A module.

Conclusion

The NV4V41SF-A laser diode module is an ideal choice for many applications. Its high power, small size, and low power stability make it suitable for applications such as spectroscopy, barcode reading, laser pointers, and visible light communication. Its optical pumped semiconductor laser diode technology and mirror cavity make it easy to use in a wide range of applications.
