Performance comparison between LWE-131 (old) and GE-100 (new) oscillators
Data represent performance observed in the past few weeks under optimum temperature conditions. Stability of new oscillator includes temporary support and transport optics, and no enhanced temperature and acoustic noise isolation.
| Phase jitter* | Phase drift | Power jitter | Power drift | Pointing jitter | Pointing drift | |
| LWE-131 | ~200 fs rms | 0.5
ps/hour
3 ps/day |
<0.4% rms | up to 10%/day | 1.5 mradian rms | 20 mradian/day |
| GE-100 | ~200 fs rms | 0.5
ps/hour

<0.1% rms | 2.5%p-p/day | 0.5 mradian rms | 10 mradian/day |
Jitter is a shot-to-shot measurement with statistics calculated over a few minutes.
* Phase jitter measurement has lower frequency limit of a few Hz.
Drift is measured over hours or days.
| LWE-131 | GE-100 | |
| Average Power | 60 mW | 400 mW |
| Pulse Duration FWHM | 20 ps | 7 ps |
| Amplified Pulse Duration FWHM | 20 ps | 14 ps |
| Realignment Frequency | > daily | 2-3 times weekly |
