This paper describes different methods to control the output power of a DPSS laser, starting from basic current control towards power control whilst maintaining all other optical parameters. This is enabled by Novanta’s proprietary ULTRALOQTM technology combined with an onboard, extra-cavity variable optical attenuator. This work focuses on the characterization of the noise profile, power stability, spectral behavior and beam profile under varying temperatures and output power levels. It is shown that the performance of the GEMultra is stable over the complete power range ranging from 100mW up to 2W.
