Options
Tunable cavity length by high-bandwidth piezo-controlled synchronization.
Feedback electronics to phase lock pulses to an external clock (see product page for more details).
All-in-one synchronization solution: laser and synchronization electronics all components from one supplier: full automation for hands off operation, integrated and tested for an immediate start. Best performance with more time for your experiments!
Synchronization: Laser to reference
Relative Phase Noise between stabilized laser and 10 MHz reference:
RMS Timing Jitter: < 200 fs [0.1 Hz – 500 kHz] or same as reference, whichever applies first.
Integrated timing jitter of free running laser: < 2 fs [rms, 10 kHz.. 1 MHz]
Synchronization: Laser to laser
Relative Phase Noise between two lasers in master-slave configuration.
RMS Timing Jitter down to < 20 fs [0.1 Hz – 500 kHz] for Menlo fs lasers as master/slave with small locking bandwidth.
Integrated timing jitter of free running laser: < 2 fs [rms, 10 kHz.. 1 MHz]
Factory-set value selectable in the 50 – 100 MHz range.
Seeding of multiple amplifiers with optional subsequent frequency conversion to cover multiple wavelengths.
Compression of second harmonic output pulse length to < 70 fs
