SHG output power vs absorbed pump power for different BiBO lengths. The inset shows the experimental setup.
Integrated mode spectrum for a frequency doubled OPS disk laser with a linear resonator and an intracavity etalon. The single measurements exhibit only one mode (dashed line). Mode hopping occurs between more than ten positions. The peak intensities indicate how much a mode position contributes to the total output power. The inset shows the dynamic of one of the modes and is similar for all main modes.
Emission spectra (left) and the corresponding output fluctuations (right) of the frequency doubled laser for different wavelength separations. The dashed lines in the upper spectrum refer to the infrared scale at the top.
Emission spectra (left) and the corresponding output fluctuations (right) for pure output and for combined and output.
