Coherent debuts high-power pump lasers for submarine and terrestrial applications

Technologies and Products

Coherent Corp. has launched high-power, uncooled pump laser modules built on the latest G10 series laser diode technology. The new modules are developed for high-reliability submarine applications and both single- and dual-chip terrestrial applications. The modules are designed for high-power, high-functionality optical amplifiers and amplified ROADM line card applications. In a compact 10-pin form factor, Coherent says the uncooled pump laser modules deliver market firsts:

  • Up to 1000 mW of output power for submarine applications.
  • Up to 2×700 mW with both symmetrical and asymmetric options on the dual-chip platform.

The uncooled modules support the growing trend toward energy-efficient networks to meet sustainability goals. This, says the company, results in a lower cost of network ownership by reducing overall power consumption and eliminating much of the thermal and power management equipment associated with legacy cooled lasers.

Qualification of the new single- and dual-chip terrestrial modules will complete in mid-2024. Samples are available now, and volume production will commence in late 2024.

“Coherent released its first uncooled pump laser module in 2004 and its first dual-chip module in 2011 and is the leader in both uncooled and dual-chip technology,” said Dr. Beck Mason, executive vice president, Telecommunications. “Our newest G10 pump chips underpin the successful evolution of our high-power uncooled pump laser modules. Together with a broad portfolio of active and passive components, Coherent offers a leading portfolio of solutions for submarine and terrestrial amplifier designers.”
