Molecular Characterization of Human Tissue Samples by Raman Spectroscopy with Different Laser Modes and Excitation Wavelengths
… of both excitation wavelengths and optical modes. Different optical modes, single mode and multimode lasers, with the same excitation 785 nm and different excitation wavelengths, 785 nm and 830 nm lasers with the same multimode are compared here. According to this study, autofluorescence and …

Terahertz oscillation and stimulated emission from planar microcavities
… of the light wavelength, where the photonic modes are con- fined and the number of states is limited. In the smallest microcavities, i.e. micrometer sized optical resonators, the propagation of only one mode is permitted that is simultaneously amplified internally. This particularly strong …

Tapered waveguide lasers
… the design and fabrication of tapered waveguide lasers to allow efficient, high-power diode-pumping and produce diffraction-limited, near-symmetrical output, whilst maintaining a monolithic design compatible with integrated optical circuits. <br/><br/>The design rules required for efficient …

Entangling the spatial properties of laser beams
… for the position and momentum of two laser beams. The position and momentum observables for laser beams manifest themselves as the displacement and tilt of the beams, and entanglement relies on the used of squeezed TEM?? laser modes, mixed with a TEM?? reference mode. The result of the …

Semiconductor laser mode engineering via waveguide index structuring
Semiconductor laser diodes are used in many applications, and their performance is often strongly influenced by the optical mode properties. In this work, dielectric waveguides and their guided modes have been simulated and analyzed as relevant to semiconductor diode lasers. The transverse …
