Coherent Corp. announced new 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 new uncooled pump laser modules are designed for high-power, high-functionality optical amplifiers and amplified ROADM line card applications. In a compact 10-pin form factor, the uncooled pump laser modules deliver market firsts: Up to 1000 mW of output power for submarine applications. Up to 2x700 mW with both symmetrical and asymmetric options on the dual-chip platform.

These uncooled modules support the growing trend toward energy-efficient networks to meet sustainability goals. This 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 digital modules will complete in mid-2024.

Samples are available now, and volume production will commence in late 2024.
