Photonics and optics technology producers, suppliers, and customers from various industries utilise lasers in manufacturing, precision instruments, scientific research, and departments related to leisure, medical, automotive, aerospace, military, research, educational, and civilian purposes, among various others. Laser technology became almost ubiquitous with the introduction of CD-ROM and optical drive technology. However, lasers have heavy and dangerous applications. Fundamentally, the laser is an emission of energy.

Laser beam delivery components: The laser and the source are relatively minor aspects within the entire system for various laser technologies. Laser beam delivery components interact and vary depending on the applications, materials targeted, industry, general aim, and operating environment. Failure or substandard laser beam delivery components can result in misguided laser applications' exposure of target material to variations from the required energy/wavelengths/criteria, rendering entire material and applications obsolete/failed. 

A laser beam delivery system is a solution that aims to deliver the laser beam to the target. In most manufacturing or other applications, the target is the intended recipient of the energy, which is intended to either affect it or yield some information through the application of lasers on the target.

Components of a Laser Beam Delivery System: 

• Laser source: The source of the laser is among the primary components of a laser beam delivery system. Among typically utilised lasers, the categories are based on the compound utilised to generate it:

CO2 Lasers: CO2 lasers are utilised in industrial and cutting applications.

Fiber Lasers: Fiber lasers are finding cutting, marking, and telecommunications applications.

Diode Lasers: Diode-based lasers are finding applications in medical/telecommunications.

Nd Lasers: These are used for cutting and welding steel.

• Optics: The optics within a laser direct, shape, and manipulate the laser beam. For industrial applications, the optics used are of the high power category and must be designed to withstand thermal damage. For entertainment applications, the optics of lasers are high quality and use colour. 

• Beam delivery path: The beam delivery path is the route the laser beam must take.

• Focusing mechanism:  Adjusting and controlling the positioning of optical elements.

• Control systems: Control systems act to stabilise, regulate, and enable automation, guidance, and monitoring for safety/stability. For material processing, control systems must be elaborate and utilise advanced software integration. For entertainment applications, control systems utilise differing software and applications.

• Protection systems: In various applications, protection systems protect workers and individuals from exposure to lasers or energy.

• Thermal/cooling technology: Cooling technology may be employed in various applications.

• Diagnostics: Active monitoring of power throughout the laser's application would be required to enable integrity.

Conclusion:  Laser beam delivery components are critical to any laser technology. They vary in construction, role, operation modes, and various other nuances.
