micro-pump lasers technical

"announced new single- and dual-chip uncooled 980nm micro-pump lasers delivering up to 700mW"

Micro-pump lasers are very small laser devices in which the light-producing material is energized by a tiny integrated pump source rather than a large external laser. Think of them as a compact flashlight where the bulb and battery are built into a chip, allowing lasers to be made much smaller, cooler, and cheaper. For investors, they matter because that size and efficiency can unlock new markets and products in telecom, sensing, medical devices and consumer electronics, potentially lowering costs and expanding revenue opportunities.

coherent transmission systems technical

"Designed to support next-generation coherent transmission systems and to enable ultra-high-density"

Coherent transmission systems are communications setups that extract more information from a single cable or fiber by detecting subtle properties of the carrier signal, not just its loudness. Think of it like sending a message using both the color and the brightness of a light so you can pack many more words into the same blink. For investors, they matter because they greatly increase network capacity and efficiency, lowering the cost per bit and enabling higher-margin services and faster growth in data traffic.

optical amplifiers technical

"enable ultra-high-density multi-rail optical amplifiers, the new devices deliver higher output"

Optical amplifiers are devices that boost light signals traveling through fiber-optic cables so data can go longer distances without losing clarity, similar to a relay runner handing off a fresh sprint instead of making the original runner go farther. For investors, they matter because they are core components in telecommunications, data-center and cable networks that determine how much data can be carried, how often equipment must be replaced, and where vendors earn recurring sales and technology premiums.

single-mode technical

"Coherent’s latest uncooled single-mode micro-pump lasers deliver up to 700mW output"

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.

SAXONBURG, Pa., March 09, 2026 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, today announced new single- and dual-chip uncooled 980nm micro-pump lasers delivering up to 700mW per fiber output in a compact 3-pin module package.

Designed to support next-generation coherent transmission systems and to enable ultra-high-density multi-rail optical amplifiers, the new devices deliver higher output power, greater efficiency, and enhanced design flexibility in space-constrained environments - critical enablers for efficient scale-across networks.

As optical networks scale to meet the growing demands of AI, cloud infrastructure, and high-capacity transport, amplifier architectures must provide higher output power without increasing footprint or energy consumption. Coherent’s latest uncooled single-mode micro-pump lasers deliver up to 700mW output with less than 3W of power consumption per fiber, operating reliably across a wide temperature range from -20°C to 85°C. By eliminating the need for active cooling while maintaining high performance and thermal stability, these new micro-pumps enable customers to design denser, more energy-efficient amplifier solutions - foundational building blocks for scale-across optical systems.

“Coherent has led the uncooled pump laser market for more than two decades, beginning with our first uncooled pump lasers in 2004 and our ultra-compact micro-pump platform in 2017,” said Madhu Krishnaswamy, Senior Vice President and General Manager - Telecom Transport Business Unit at Coherent. “Our latest high-power uncooled micro-pump lasers extend that legacy of innovation and enable customers to achieve density and performance levels that were previously unattainable in compact amplifier designs for the demanding DCI application.”

Samples of the new devices are available now, with volume production expected to begin in calendar Q2 2026. Attendees of OFC 2026 are invited to visit Coherent at Booth 1401 to learn more about these high-power uncooled pump lasers and the company’s comprehensive optical component portfolio.
