Laser diodes are a form of semiconductor light source, which emit light in a narrow range of wavelengths when operated with a specific supply current. Laser diode modules are complete devices that include the diode and associated components such as optics and power supplies. The SPL CG81-2S laser diode module is a common type of module used for many different applications, and a brief description of its application field and working principle, are outlined in the following section.

Application Field: The SPL CG81-2S laser diode module is mostly used in industrial and research laser applications. It is suitable for use in laser range finders, bar code scanners, medical laser systems, military systems, and various other types of laser devices. Some of the specific applications in which the SPL CG81-2S can be found include welding, laser marking, laser cutting, 3D printing, and optical fiber communication.

Working Principle: The SPL CG81-2S laser diode module operates with a CW laser diode, which has a power output of up to 1 Watt. The module works on the principle of stimulated emission, wherein a photon is emitted from an excited state energy level of a substance as soon as it is stimulated by another photon or particle of energy. This photon then stimulates other excited state electrons in the material, allowing them to emit more photons, thus creating a chain reaction that results in the emission of Laser light.

The primary components of the SPL CG81-2S module are the laser diode, an optical system to focus the laser beams generated, an electronic driver for controlling the supply current to the laser diode, and a power supply to supply the required current to the diode. The driver is essential for controlling the laser output power and wavelength. The precise control of the driver allows the extraction of laser energy from the diode in a controlled fashion, thus maximising the output power from the module.

To demonstrate the performance of the SPL CG81-2S module, several tests were conducted, including optical output power, conversion efficiency, system efficiency, and wavelength stability. The module was able to achieve output powers as high as 950 mW with an optical system efficiency of up to 60%. Furthermore, the SPL CG81-2S laser diode module was proven to have excellent wavelength stability over a wide operating range.

In conclusion, the SPL CG81-2S laser diode module is a versatile device that is suitable for a variety of laser applications. The module features a CW laser diode that can generate output powers up to 1 Watt amid excellent system efficiency and wavelength stability. As a result, the SPL CG81-2S is a reliable and cost-effective device for a range of laser applications.
