Description

Monitoring and scanning the wavelength is mostly done by relying on wavemeters, but there are some pitfalls. Let's discuss some!

    The frequency spectrum of the dye laser amplifier in the Helios laboratory in IKS, KU Leuven, has been observed to contain sidebands of the main laser frequency. Multiple orders of these sidebands have are seen and have an offset of about 800 MHz from one another. The origin of this problem and some solutions have been investigated.
    Once the output of the laser light is a pure single mode,...
