Performance
The Piano shows very precise tunability and extreme stability
(<0.02 cm-1/h)
along with ultra-low relative intensity noise (<-160 dBc/Hz).
Modulation
The Piano is equipped with a high speed optical modulator. All outputs are modulated through a single input signal. The system comes with a fully integrated modulation architecture including a precision electronic oscillator and full software support.
| Modulation frequency | 1 kHz to 3 MHz (adjustable) |
| Frequency resolution | < 1 Hz |
| Modulation depth | 0 to 100% (adjustable) |
| Duty cycle | 0 to 100% (adjustable) |
