EVOLASE SHORT PULSE MODULE is an amplifying module containing all the needed optical components packaged inside an aluminum housing. The unit is ready-to splice to pump diodes and seed source. The pump coupling unit inside the housing is directly water cooled, and the baseplate of the unit can be easily mounted onto an external heat sink for high power applications.

This module is ideal for customers who want to have fully assembled, ready-to-splice gain unit, but prefer to use their own pump diodes or integrate the module inside a larger system.

The module is fully tested and shipped with a complete test report.

Ordering information

SPGM-PM-C2-“wavelength”-“signal fiber”-“pump fiber”-“built in base cooling”
Signal fiber: 10/125
Pump fiber: 105/125, 200/220, 220/24
Built in base cooling to support high power operation more than 50 W output and eliminates the need to attach the module base to an external heat sink: 0 – no built-in base cooling, 1 – built-in base cooling.
