Santec TSL-710 - Coherence Control; Tunable Semiconductor Laser TSL-710

Tunable Semiconductor Laser TSL- 710
6-3
A function used to increase the spectral linewidth of the output light. The coherence of
the light is reduced by increasing the linewidth, and the uctuation of the optical power
by interference can be suppressed.
If the uctuation of the optical power becomes a problem due to inuence from the
reecting point in the system using this device, use this function.
■
How to set
1. Press Menu (F4 key) → Coh. C (F1 key) on the main screen.
2. The coherence control function turns ON, and “Coh.Ctrl” lights up on the right edge
of the screen.
■
How to cancel
1. Press Coh. C (F1 key).
2. The coherence control function turns OFF, and “Coh.Ctrl” turns off on the screen.
6-2 Coherence Control
F1 key
Coherence control cannot be changed to ON, when modulation setting is “Ext.”.
Please check modulation setting is set to “Disable”, before using coherence control.
