Laser fringe lockers are devices that are used to stabilize the frequency of lasers by locking the laser’s frequency to an external reference.
Quantum cascade lasers are unique in that they rely on a series of energy levels, or “cascades,” within the device to create and amplify light.
External cavity diode lasers (ECDLs) are a type of laser that use a diode as the light-emitting element. These lasers are characterized by their high efficiency and low cost, making them popular for many applications including telecommunications, spectroscopy, and laser printing.
Laser pointers are often thought of as a harmless tool for presentations or as a toy for children. However, 532nm laser pointers, which emit green light, can be particularly dangerous due to a number of factors.
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser to fuse together small particles of plastic, metal, or ceramic powder into a three-dimensional (3D) object.
Newton’s rings are an optical phenomenon that occurs when light reflects off a thin film of air or other transparent substance between two surfaces.
Polarizing beamsplitter cubes (PBSCs) and non-polarizing beamsplitter cubes (NPBSCs) are optical devices that are used to split an incoming light beam into two separate beams.
Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, injury to the eyes or skin, or damage to property.
A laser q-switch, also known as a Q-switched laser, is a type of laser that is designed to produce very short and high-energy pulses of light.
Laser guide stars are artificial stars created by shining a laser beam into the atmosphere. The laser beam ionizes the atoms in the atmosphere, creating a bright, artificial star that can be used as a reference point for the telescope’s adaptive optics system.
