Laser technology

Laser construction A laser consists of a gain mediuma mechanism to energize it, and something to provide optical feedback. Light of a specific wavelength that passes through the gain medium is amplified increases in power. For the gain medium to amplify light, it needs to be supplied with energy in a process called pumping. The energy is typically supplied as an electric current or as light at a different wavelength.

Laser technology

Laser[ edit ] — nm lasers are most common for non-scientific applications. Maximum power is limited by the need to make them eye-safe in applications that operate around people.

Laser technology

Laser settings include the laser repetition rate which controls the data collection speed. Pulse length is generally an attribute of the laser cavity length, the number of passes required through the gain material YAG, YLFetc. Better target resolution is achieved with shorter pulses, provided the lidar receiver detectors and electronics have sufficient bandwidth.

The power is limited to levels that do not damage human retinas. Wavelengths must not affect human eyes. However, low cost silicon imagers do not Laser technology light in the eye-safe spectrum.

Why choose us?

Controlling the timing phase of each antenna steers a cohesive signal in a specific direction. Phased arrays have been used in radar since the s. The same technique can be used with light. On the order of a million optical antennas are used to see a radiation pattern of a certain size in a certain direction.

Laser technology

The system is controlled by timing the precise flash. Specific sub-zones can be targeted at sub-second intervals. By contrast, solid-state lidar can run forhours.

However, their tiny form factor provides many of the same cost benefits. A single laser is directed to a single mirror that can be reoriented to view any part of the target field. The mirror spins at a rapid rate. However, MEMS systems generally operate in a single plane left to right.

To add a second dimension generally requires a second mirror that moves up and down. Alternatively another laser can hit the same mirror from another angle. Options to scan the azimuth and elevation include dual oscillating plane mirrors, a combination with a polygon mirror and a dual axis scanner.

Optic choices affect the angular resolution and range that can be detected. A hole mirror or a beam splitter are options to collect a return signal.

Fundamental principles

Photodetector and receiver electronics[ edit ] Two main photodetector technologies are used in lidar: The sensitivity of the receiver is another parameter that has to be balanced in a lidar design.

Position and navigation systems[ edit ] Lidar sensors mounted on mobile platforms such as airplanes or satellites require instrumentation to determine the absolute position and orientation of the sensor.Genius Laser Technology (GLT) is an innovative Melbourne based Australian, laser show production company, offering an extensive range of laser shows, products and services to the events and entertainment industry.

Learn The Fundamentals of Laser Technology. What is a Laser? A laser is a device that emits a beam of coherent light through an optical amplification process. There are many types of lasers including gas lasers, fiber lasers, solid state lasers, dye lasers, diode lasers and excimer lasers. All of these laser types share a basic set of components.
