Coherent was founded in May 1966 by physicist James Hobart and five cofounders. It went public in 1970. Over time, Coherent acquired other laser businesses and expanded to lasers for different industries and applications. From 2004 to 2021, it grew from $400 million to almost $2 billion in revenues, in part through a series of acquisitions.
In 2022, II-VI acquired laser manufacturer Coherent, Inc.. [14] and took the name Coherent Corp. Carl Johnson served as II-VI's first CEO from 1985 to 2007. He stepped down as CEO in 2007 and was named chairman of the board, a position he held until 2014. [15] Johnson was succeeded as CEO by Francis Kramer, who had been president since 1985. [13]

PITTSBURGH, Oct. 21, 2024 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in industrial laser technology, announced the launch of the EDGE FL TM high-power fiber laser series, tailored for cutting applications in the machine tool industry. Available with power levels from 1.5 kW to 20 kW, the EDGE FL series redefines the ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
In forward-detected SRS, the modulated laser is blocked by a high OD notch filter and the other laser is measured by a photodiode. Modulation transferred from the modulated laser to the originally unmodulated laser is normally extracted by a lock-in amplifier from the output of photodiode. In epi-detected SRS, there are normally two methods to ...
The free-electron laser FELIX Radboud University, Netherlands. A free-electron laser ( FEL ) is a fourth generation light source producing extremely brilliant and short pulses of radiation. An FEL functions much as a laser but employs relativistic electrons as a gain medium instead of using stimulated emission from atomic or molecular excitations.
A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. The first working laser was a ruby laser made by Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960. [1] [2] Ruby lasers produce pulses of coherent visible light at a wavelength of 694.3 nm, which is a deep red color.
