Topcon Positioning Systems Inc., provides positioning technology for surveyors, civil engineers, construction contractors, equipment owners and operators. Topcon Corporation acquired Advanced Grade Technology in 1995 and became known as Topcon Laser Systems.
Ophthalmic company, Topcon Corp. has distributed the PASCAL system since 2008, and acquired OptiMedica's retina and glaucoma technology in August 2010. Ophthalmic laser delivery systems. Most ophthalmic laser delivery systems include: A laser source, such as the Nd:YAG laser used in Pascal
SHJ has the highest efficiency amongst crystalline silicon solar cells in both laboratory (world record efficiency) [2] [27] [29] and commercial production (average efficiency). In 2023, the average efficiency for commercial SHJ cells was 25.0%, compared with 24.9% for n -type TOPCon and 23.3% for p -type PERC. [34]
This is a list of laser types, their operational wavelengths, and their applications. Thousands of kinds of laser are known, but most of them are used only for specialized research.
Laser communications in deep space will be tested on the Psyche mission to the main-belt asteroid 16 Psyche, launched in 2023. The system is called Deep Space Optical Communications (DSOC), and is expected to increase spacecraft communications performance and efficiency by 10 to 100 times over conventional means.

Theodolite. A direct-readout theodolite, manufactured in the Soviet Union in 1958 and used for topographic surveying. A theodolite ( / θiˈɒdəˌlaɪt /) [1] is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is ...
Website. lle.rochester.edu. The Laboratory for Laser Energetics ( LLE) is a scientific research facility which is part of the University of Rochester 's south campus, located in Brighton, New York. The lab was established in 1970 with operations jointly funded by the United States Department of Energy, the University of Rochester and the New ...
Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light. They are also used in optical parametric oscillators and some interferometers. Light confined in the cavity reflects multiple times, producing modes with certain resonance frequencies.
With a suitable range of periods, output wavelengths from 700 nm to 5000 nm can be generated in periodically poled lithium niobate (PPLN). Common pump sources are neodymium lasers at 1064 nm or 532 nm. An important feature of the OPO is the coherence and the spectral width of the generated radiation.
