64-fs ultrashort pulse generation from a Kerr-lens mode-locked (Yb0.058Sc0.508Y0.434)2O3 ceramic laser
Abstract:
We have successfully used a mixed sesquioxide ceramic (Yb0.058Sc0.508Y0.434)2O3 (Yb:YScO3) as a gain medium for femtosecond laser generation via Kerr-lens mode-locked laser technology. A high-brightness diode laser has been used for pumping the ceramic sample, and a stable pulsed laser with a time duration of 64 fs and an average output power exceeding 100 mW at a peak wavelength of 1046 nm has been achieved. This is the first, to the best of our knowledge, report of femtosecond laser operation using mixed sesquioxide ceramic as a gain medium, and the time-domain width of the obtained pulsed laser is also one of the shortest in Yb-doped ceramic material mode-locked lasers.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
