Abstract:
Continuous output from a Nd:YVO₄ crystal around 1073 nm was studied. The output of 1064 nm was suppressed with a Type I phase-matching LiB₃O₅ (LBO) crystal rotated by 45°. With a pump power of 4.5 W, a 300 mW continuous output at 1073 nm was achieved for what we believe is the first time, and the optical-to-optical efficiency was 7%. With an adjustable LBO crystal, the wavelength is tunable from 1073.2 to 1073.5 nm. Even simultaneous output of 1066 and 1073 nm was realized by adjusting the LBO crystal. The experiments proved related theoretical analysis.

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...
