Laser diodes are semiconductor devices that produce laser light by a form of stimulated emission of light effect. A laser diode is a solid-state device that emits light of a single wavelength, within a very narrow spectrum of the visible spectrum. It is often used for laser light sources and laser lighting effects. The VLM-650-04 LPA is one such device.

The VLM-650-04 LPA is a laser diode in module form. It consists of a laser diode and an associated laser driver circuitry, power supply, and controls. It has a wide range of applications, and is well-suited to all kinds of laser light displays, laser projectors, laser marking systems, and laser-based medical and industrial processes.

The VLM-650-04 LPA is a mid-power laser diode module at 650nm, with a wavelength of 645nm to 649nm, and an output power of 4mW. It has a beam divergence of ≤1.2mrad and an output power stability of ≤3%. The module is designed to be reliable and efficient, with a long expected operational lifetime. It features a built-in driver with a microcontroller and an adjustable current output, allowing for rotary and PWM control.

The working principle of the VLM-650-04 LPA is based on the stimulated emission of light (SE) effect. When a beam of electrons passes through the module, it stimulates the emission of light with a determined wavelength. The electrons are supplied from either the electrical current or a light source, such as a laser. As the electrons pass through the module, they excite atoms and molecules in the module, which emit light of certain wavelengths. This light is then amplified by passing through an optical resonator, and is emitted as a laser beam.

The VLM-650-04 LPA is a versatile and powerful module for many laser light applications. It is well suited to laser light displays, laser projectors, laser marking systems, and laser-based medical and industrial processes. With its wide range of applications, the VLM-650-04 LPA is an excellent choice for any laser light source.
