Question of the day:
Do you know the real spectral linewidth of your laser?

It's notorously difficult to determine the actual linewidth of a laser that's below, say, 500 kHz.

But the EagleEye is a unique instrument that offers an accurate and straightforward way to measure linewidth values to as narrow as 20 kHz.

Learn first about Scan Mode, then explore the High Time-Resolution Mode.
