    摘要: The present invention concerns an optical molecular sensing device and related method. The optical molecular sensing device has an optical resonator adapted to be connected to an excitation source. The excitation source may be a laser operating at a 2.7-2.8 um spectral range. The optical molecular sensing device has an emission spectrum comprised of a plurality wavelengths. Also included are a detection unit and a RF frequency counter to detect at least one RF beat note resulting from detecting the emission spectrum of the optical resonator. A change in frequency of the RF beat note indicates the presence of a target molecule.

    摘要: The present invention relates to a Q-switching-induced gain-switched erbium pulse laser system, capable of generating erbium laser pulses within the 2.5 μm to 3.0 μm wavelength region, by means of Q-switching operation at 1.6 μm. At first, an Er3+-doped gain medium is pumped and Q-switched at the wavelength region from 1.58 μm to 1.62 μm, so that a Q-switched pulse is formed from the Er3+-doped gain medium. The Q-switched pulse results in an instant positive population inversion between the levels 4I11/2 and 4I13/2 of the Er3+-doped gain medium, followed by a gain-switched laser pulse at the wavelength region from 2.5 μm to 3.0 μm.

    摘要: An optical amplification system has an active fibre section having an optical fibre 10 and containment means 8, 12 containing light of a specific wavelength within the active fibre section. The specific wavelength of light is the result of the spontaneous transition of photons. The contained photons stimulate further photons emissions, which depopulates energy levels involved in the amplification process.

    摘要: An optical material comprises a host matrix (e.g. fluorozirconate glass such as ZBLANP) doped with an optical atom pair or ion pair, each pair comprising a sensitizer (e.g. Nd.sup.3+) and an activator (e.g. Pr.sup.3+). The sensitizer is capable of absorbing optical excitation energy of a single wavelength (e.g. in the 800 nm region of GaAlAs diode laser) and transferring this optical excitation energy to the activator. This causes emission of visible and/or infrared light when the activator relaxes back into any of its lower energy states. Optical devices containing the optical material, and methods for generating visible and/or infrared light involving the optical material are also disclosed.
