Laser diodes, also known as laser light-emitting diodes (LDs), are tiny devices that generate coherent light radiation using diode technology. They consist of a tiny active region of semiconductor sandwiched between two or more highly reflective end-facets. Laser diodes can be used as both an emitter and detector for various applications need a high-intensity light source, ranging from the telecommunications industry to medical.

A VLM-635-18 LPA is a laser diode module (LDM) that is used in various optical systems to convert a pulsed laser beam into a continuous beam. It has an 18mm long active region, and an operating wavelength range between 635nm and 680nm. The VLM-635-18LPA boasts a moderate optical power of up to 120mW with good thermal performance, making it highly suitable for applications like fiber-optic communication systems and medical laser systems.

The main application field of a VLM-635-18 LPA laser diode is fiber-optic communication systems, as it is capable of providing high power as well as an adjustable operating current for improved performance. The operating current range is typically between 5-20mA, with the operating voltage ranging between 1.1V to 1.7V. This makes it capable of providing stable output power and intensity even when exposed to wide temperature ranges and other environmental factors. Moreover, the beam divergence angle of this diode is usually between 20-30mrad (milliradians), making it suitable for use in systems that require a precise beam pattern.

The working principle of the VLM-635-18LPA is based on the fact that the electrical current passing through it generates a direct current in the active region, which then allows a stimulated emission process to occur. As a result, a “beam” of coherent light is emitted from the diode, which is then focused and amplified by the optical components of the system. The optical components can be mirrors, lenses, and other components which allow the beam to be focused to the desired output power. Additionally, the active region can be pumped with electrical current to further increase the beam intensity.

In summary, the VLM-635-18LPA laser diode is a versatile and high-performance diode module that is ideal for applications that require a high-intensity light source with good thermal performance. It has a wide operating current range and its beam divergence makes it suitable for precise beam patterns. Moreover, its stimulated emission process allows it to generate a good amount of coherent light, making it highly suitable for use in optical communication systems and other medical applications.
