Laser Description
3-17
1
Specifications subject to change without notice and only apply when the Lok-to-Clock Tsu-
nami system is pumped by a Spectra-Physics Millennia laser. For output characteristics,
refer to the tables at the end of Chapter 3.
2
Measured over 1 second with respect to the internal 80 MHz oscillator over a 2- hour
period after a 1-hour warm-up and less than ±1°C temperature change.
3
Performance with external reference input is dependent upon the quality of the reference
signal. For requirements on the external reference repetition rate, call your local
Spectra-Physics representative.
4
Testing for other wavelengths is in progress; call your local Spectra-Physics representa-
tive for current information.
5
As measured between the laser output pulse and the internal 80 MHz reference oscilla-
tor, over a bandwidth of 100 Hz to 10 kHz.
