High Power Narrow Linewidth YDFA

Amonics’ High Power YDFA series offer saturated output power from 0.5W to 20W. It is a standalone turnkey device, available in benchtop or rackmount casing.

The front panel includes a LCD monitor display, key switch, power adjust control knob, and fiber input and output adaptors. A RS232 computer interface is provided for control and monitoring. This YDFA is well suited for R&D in the fields of free space sensing and 532 nm second harmonic laser generation.
