Key Terms

optically pumped semiconductor, super-resolution microscopy, dna sequencing, quantum sensing, +4 more

8 terms

optically pumped semiconductor technical

"based on the company’s proven Optically Pumped Semiconductor (OPS) technology."

An optically pumped semiconductor is a semiconductor device that produces laser light when it is energized by another light source rather than by an electric current; think of shining a bright lamp on a specially designed chip to make it emit a focused beam. Investors care because this approach can offer higher efficiency, cleaner wavelengths and easier tuning than some traditional lasers, affecting product performance, manufacturing costs and market opportunities for companies in communications, manufacturing, medical devices and sensing.

super-resolution microscopy medical

"Advanced life science applications such as super-resolution microscopy and DNA sequencing require"

Super-resolution microscopy is a set of imaging techniques that let scientists see structures inside cells and materials at much finer detail than conventional light microscopes—think upgrading from a blurry zoom to a high-resolution photograph that reveals tiny features. For investors, it matters because those clearer images can speed drug discovery, improve diagnostics, and enable new medical devices or quality-control tools, creating potential revenue and competitive advantages for companies that develop or use the technology.

dna sequencing medical

"Advanced life science applications such as super-resolution microscopy and DNA sequencing require"

Determining the order of the chemical “letters” that make up an organism’s DNA, much like reading the pages of an instruction manual for cells. For investors, DNA sequencing matters because it underpins many products and services—diagnostic tests, targeted drugs, and personalized treatments—so advances or cost reductions can create new revenue streams, change competitive positions, and affect regulatory and technical risk for companies in health and biotech.

quantum sensing technical

"Emerging quantum sensing, holography, and semiconductor applications further demand ultra-low noise"

Quantum sensing uses the unusual behavior of tiny particles to measure physical quantities—like magnetic fields, time, or motion—with far greater precision than conventional sensors. For investors, it matters because this leap in sensitivity can enable new products and markets (better medical imaging, navigation without GPS, or faster material testing), potentially creating high-growth opportunities for companies that commercialize reliable, scalable devices.

holography technical

"Emerging quantum sensing, holography, and semiconductor applications further demand ultra-low noise"

Holography is a way of recording and projecting light so that images appear three-dimensional, like a photograph you can walk around rather than a flat picture. For investors, it matters because holography underpins products and services—from advanced displays and secure packaging to data storage and medical imaging—so breakthroughs or commercial adoption can create new revenue streams, competitive advantages, or shifts in supply chains and intellectual property value.

acousto-optic modulators technical

"eliminates the need for external components such as Acousto-Optic Modulators, reducing cost"

Acousto-optic modulators are small devices that use sound waves inside a solid crystal to change a light beam’s brightness, color (frequency), or direction—think of ripples in water redirecting a stream of light. Investors care because these components enable and improve lasers, fiber-optic communications, imaging systems, and precision manufacturing; their performance, cost, and availability can directly affect the competitiveness and revenue potential of companies that build or use advanced optical products.

single-mode technical

"supports customized wavelengths and optional single-mode or multi-mode fiber coupling."

Single-mode describes a type of optical fiber or laser that carries light along one path or “mode,” similar to a single-lane highway that avoids traffic jams. For investors, single-mode technology matters because it supports higher data rates and longer-distance communications with lower signal loss than multi-path alternatives, affecting costs, network performance and demand for telecom and data-center infrastructure.

multi-mode technical

"supports customized wavelengths and optional single-mode or multi-mode fiber coupling."

Multi-mode describes a product, system, or service that can operate in more than one way or under multiple conditions — for example switching between different technologies, treatment approaches, or user settings. For investors it signals flexibility to reach more customers, adapt to changing regulations or needs, and potentially reduce reliance on a single market, though it can also mean higher development costs or greater regulatory complexity; think of it like a Swiss Army knife versus a single-purpose tool.

SAXONBURG, Pa., Jan. 15, 2026 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, today announced the launch of the Sapphire XT, a new mid-power visible laser platform based on the company’s proven Optically Pumped Semiconductor (OPS) technology. Sapphire XT debuts as an impressively compact, one-box solution with an integrated controller and available at 488nm, 532nm, and 561nm, each delivering 1W of output power. This new laser system has a footprint comparable to a smartphone, doubling the performance of previous models while reducing the overall size by more than 50%.

Advanced life science applications such as super-resolution microscopy and DNA sequencing require laser wavelengths precisely aligned with fluorescent dyes absorption peaks, along with increased output power for higher resolution and throughput. Instrument manufacturers seek to reduce system complexity and cost through greater laser integration by incorporating more functionality directly into the laser. Emerging quantum sensing, holography, and semiconductor applications further demand ultra-low noise, long-term power stability, and exceptional reliability.

Sapphire XT meets these needs by offering a fully integrated laser platform that introduces intrinsic modulation enabled by OPS technology. Its direct electrical modulation interface eliminates the need for external components such as Acousto-Optic Modulators, reducing cost and simplifying integration. The system supports customized wavelengths and optional single-mode or multi-mode fiber coupling. Compatibility with the Coherent OBIS XT platform extends coverage to 640nm in the red spectral region and key UV wavelengths between 261nm and 360nm. Together, Sapphire XT and OBIS XT enable multi-wavelength solutions (488nm, 561nm, and 640nm) for super-resolution microscopy, all with matched form factors and 1W power levels to help reduce significantly build spaces and control architecture complexity.

“Our Sapphire XT platform represents a major step forward in compact lasers for the visible spectrum,” said Dr. Torsten Rauch, Senior Vice President, Solid State Business Unit. “Combining unmatched OPS technology with advanced manufacturing, we are setting a new standard for compact, high-power visible lasers that enable the next generation of life science and semiconductor innovations.”

Coherent will showcase the new Sapphire XT platform at BiOS Expo & Photonics West 2026 from January 17 to January 22, 2026, at the Moscone Convention Center in San Francisco.
