This radiation is tuned to at least one wavelength in the fingerprint region of the infrared spectrum. A detector (32) detects radiation backscattered from the target (5). An analyser determines from at least the presence or absence of detected signal in said at least one wavelength whether a predetermined volatile compound is present. An associated detection method is also provided. In embodiments, the laser source is tunable over a plurality of wavelengths, and the detector comprises a hyperspectral imaging system. The laser source may be an optical parametric device has a laser gain medium for generating a pump beam in a pump laser cavity, a pump laser source and a nonlinear medium comprising a ZnGeP2 (ZGP) crystal. On stimulation by the pump beam, the ZnGeP2 (ZGP) crystal is adapted to generate a signal beam having a wavelength in a fingerprint region of the spectrum and an idler beam having a wavelength in the mid-infrared region of the spectrum. The laser gain medium and the ZnGeP2 (ZGP) crystal are located in the pump wave cavity.

摘要： A radial polarization disk laser, including a pumping source, a collimator lens, a focusing lens, a laser gain medium, a Brewster axial cone, and a output lens, which are sequentially arranged along a laser light path. An angle formed between the conical surface and the bottom surface of said Brewster axial cone is a Brewster's angle. Said laser gain medium is bonded with said bottom surface; said laser gain medium and said output lens form a laser harmonic oscillator cavity therebetween. The pumped laser light emitted by said pumping source passes through said collimator lens and said focusing lens, then is focused on the laser gain medium, and. the generated photons oscillate in said laser harmonic oscillator cavity, and then a radial polarized laser beam is finally output by said output lens.

摘要： The disclosed invention relates to a method of realizing an oxygen laser oscillator. The laser oscillator relating to one aspect of the invention is provided with a laser cavity consisting of a high-reflectivity mirror (108) and a partial-reflectivity output mirror (107), a singlet oxygen generator (105), a focusing optics (109), and a shutter (113). Singlet oxygen (O2(1Δg)) is supplied to the chamber (102A) which is pumped beforehand by a vacuum pump. In order to produce a laser oscillation, the shutter (113) is pulled out so that the radiation from O2(1Δg) goes back and forth inside the laser cavity. This causes a stimulated emission from O2(1Δg), and a pulsed laser is extracted from the output mirror (107).

摘要： An optical amplifier which integrates a pre-amplifier and a power amplifier in a single rectangular active medium to enable amplification of low power ultra-short pulses to optimal power levels. A seed beam passes through the amplification medium along a first pre-amplification path making multiple traverses of the medium. It is imaged back along the first path to make a double pass of the medium as a pre-amplifier. The beam is then re-imaged into the medium again on a second power amplification path, making multiple traverses of the medium in a single pass. The paths are independent but overlap so that efficient power extraction is achieved. Embodiments based on all passive components are described.

摘要： The invention relates to a mirror arrangement for guiding a laser beam in a laser system having at least one first end mirror and one second end mirror, wherein said end mirrors define a resonator having an optical resonator axis, wherein the laser beam is guided into the resonator as an input laser beam and is guided out of the resonator again after multiple reflection at the first and second end mirrors as an output laser beam. The sequence of reflections at the first and second end mirror thereby determines a direction of rotation between the first and second end mirror, defined as an axis of rotation relative to the resonator axis, whereby a first beam path is defined and the laser beam circulates in a direction of rotation between the first and second end mirrors in the resonator defined as an axis of rotation relative to the resonator axis. The resonator is designed such that the direction of rotation is reversed at a reversing point and the laser beam in the resonator passes through at least partially in a direction of rotation opposite to the first beam path, whereby a second beam path is defined.

摘要： A laser system may include a solid-state laser gain material (LGM) module. The system may also include a multi-pass resonator including a plurality of relay mirrors. The plurality of mirrors may be grouped at least in pairs. A first mirror of each pair of relay mirrors may be positioned to cause a laser beam from the LGM module incident on the first mirror to be reflected to the second mirror, and the second mirror may be positioned to reflect the laser beam back to the LGM module for further amplification. The multi-pass resonator may be configured to provide a high-quality laser beam in the fundamental mode.
