How to Avoid Excessive Power?

set an output power level that is larger than the laser diode can produce at
the selected wavelength.
To avoid this you can:
• reduce the optical output power,
•click Set P
max
in the Setting option to select the highest permissible
power for the selected wavelength.
•click Set P
max
/Sweep to select the highest permissible power for the
selected wavelength sweep.
How to Perform a Wavelength Sweep?
What is a Wavelength Sweep?
A wavelength sweep is performed when the instrument changes the
optical wavelength of the optical output across a user-defined wavelength
range. You can use a wavelength sweep to measure the
wavelength-dependent loss of an optical component.
How to Set the Wavelength Sweep?
The wavelength sweep can be set up through the Sweep VIEW tab.
