Repetition Rate Locking for PHAROS

Phase noise data of PHAROS oscillator locked to a 2.8 GHz RF source

Phase noise data of PHAROS oscillator locked to a 2.8 GHz RF source.

Timing jitter stability over 14 h; PHAROS oscillator locked to a 2.8 GHz RF source

Timing jitter stability over 14 h; PHAROS oscillator locked to a 2.8 GHz RF source.

The oscillators in PHAROS lasers can be customized for repetition rate locking applications. Coupled with the necessary feedback electronics, the oscillator’s repetition rate can be synchronized to an external RF source using the two piezo stages installed within the cavity.

The repetition rate locking system ensures an integrated timing jitter of less than 200 fs for RF reference frequencies above 500 MHz. Additionally, continuous phase shifting is available upon request.
