TOPTICA PHOTONICS AG - High-end laser systems for your scientific or industrial application

TOPTICA Photonics AG offers a wide range of optical fibers ideally suited for use with TOPTICAs lasers and FiberDock. These economically priced fibers cover a wide range of wavelengths. TOPTICA recommends to always purchase a fiber along with a laser and fiber coupler, as this ensures maximum fiber coupling efficiency.

CoSy generates both purely Doppler-free and purely Doppler-broadened absorption saturation spectra, which can be fed directly to appropriate stabilization electronics. CoSy can conveniently be used for top-of-fringe stabilization with a modulation technique (bandwidth 50 kHz .. 1 MHz). The CoSy module helps the customer save time and space in his experiment. The absorption cell of the Cosy is filled with Rb, Cs and K and serves as a frequency reference for Rb, Cs and K frequencies from a single device.

The FiberOut fiber collimator transforms the divergent beam emitted at the end of an optical fiber into a collimated one. It can be equipped with a variety of lenses, matching different fiber mode-field diameters and output beam sizes. The rugged, inexpensive collimator can be used for both FC/PC and FC/APC-type connectors. It can be easily mounted on post or into optical mounts (25 mm diameter).

The FiberDockTM is an easy-to-use fiber coupler, suitable for both TOPTICA laser systems and third party lasers. Its patented design (US 7,321,706, EP 1,666,944) enables highest coupling efficiencies, combined with an impressive long-term stability. Based on the individual laser parameters such as wavelength (range 350 nm to 2800 nm), beam diameter and the mode field diameter of the coupled fiber, a suitable focusing lens is selected and integrated inside the FiberDockTM.

The FPI 100 is a confocal, scanning Fabry-Perot interferometer with a built-in photodetector unit, designed for measuring and controlling the mode profiles of continuous wave (cw) lasers. The FPI is available with different mirror sets and photodetectors for wavelength ranges between 330 nm and 3000 nm. The standard mirror reflectivity is 99.8 %, corresponding to a typical finesse of > 400, resolving even narrow laser lines.

Distributed feedback (DFB) laser diodes feature a grating structure within the semiconductor and thus operate in both longitudinal and transverse single mode. Tuning is achieved by modulating either the laser current or the chip temperature. Mode-hop free tuning is maintained over several hundred GHz. Applications include alkaline spectroscopy, laser cooling, gas detection and the generation of tunable cw terahertz radiation.

Tapered amplifier (TA) diodes combine the "best of both worlds": They amplify laser radiation into a nearly diffraction limited beam to powers that would destroy the facets of normal laser diodes. At the same time the spectral properties of the master laser are preserved. TOPTICA offers TA chips separately, but also integrates them into convenient laser systems (TA pro and BoosTA)

The wavelength meters of the WS series accomplish wavelength measurements with highest accuracy. Both cw and pulsed lasers with narrow-band emission can be examined, monitored and even actively controlled. Various models of the WS series are available, covering UV to IR wavelength ranges (192 nm - 11 µm). Based on a rugged Fizeau interferometer setup without any moving components, the wavelength meters provide quasi unlimited lifetime.The spectrum analyzers LSA and HDSA allow for multi-line or broadband spectrum of light sources like cw and pulsed lasers, gas discharge lamps, super luminescence diodes, semiconductor laser diodes and LEDs.
