Raman amplifiersS ERaman amplifiers from TOPTICA Photonics

Our new highly reliable Raman fiber amplifiers are based on patented new technology. With their high power up to 30 W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fiber amplifiers. With a tuning range of 10 nm and a relative intensity noise <1% r.m.s., TOPTICA offers its own portfolio of RFAs that can be seamlessly integrated with TOPTICA lasers as seeders and frequency converters to reach visible and UV wavelengths.

Raman spectroscopy equipmentS ERaman spectroscopy equipment from TOPTICA Photonics

For Raman spectroscopy, a wavelength of 532 nm is regularly used, as well as 785 nm (to reduce autofluorescence of the sample). For semiconductor inspection shorter wavelengths of 405 nm, 266 nm, or even 213 nm are commonly used.

Most recent, upcoming time-resolved Raman spectroscopy and microscopy applications (i.e measurements on airplane engine exhausts to optimize the combustion process and reduce fuel consumption) trigger the need for pulsed laser sources operating in the femto- and picosecond regime. This demand is covered by the FemtoFiber laser family, which have already proven its outstanding performance and suitability in various broadband CARS and SRS applications.

red lasersS Ered lasers from TOPTICA Photonics

TOPTICA offers a large variety of wavelength-selected single-mode laser diodes. Among more standard laser diodes you will also find "rarities", i.e. diodes with output wavelengths that only TOPTICA provides. The diodes can be purchased separately. In addition TOPTICA can integrate any diode from the stock lists into a tunable diode laser system: Fabry–Perot or AR-coated laser diodes may be integrated into a diode laser systems, DFB/DBR laser diodes into a DFB pro and Tapered Amplifier into an TA system.

Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet. In case you can still not match your wavelength of choice, contact TOPTICA – and chances are very high that we can provide it within very short time.

TOPTICA offers industrial and research grade lasers for spectroscopy with an ultra-broad wavelength coverage: 190 nm – 0.1 THz. TOPTICA lasers deliver narrow-linewidth emission that is tunable – in some systems up to 110 nm wide without a single mode hop.

High-end, turn-key difference frequency combs and terahertz systems complement the portfolio for the most demanding spectroscopy applications.

supercontinuum sourcesS Esupercontinuum sources from TOPTICA Photonics

TOPTICA’s FemtoFiber ultra femtosecond fiber lasers are excellent tools for multiphoton imaging. These ultrafast lasers provide powerful pulses centered at 780 nm (500 mW average power and below 150 fs pulse duration), at 1050 nm (5 W average power with an unprecedented short pulse duration of typically 90–100 fs), as well as 1550 nm (up to 2 W power and 200 fs pulse duration). They are ideal light sources for multiphoton (SHG/THG) microscopy, supercontinuum generation, material processing, as well as OPCPA or amplifier seeding.

tapered amplifiersS Etapered amplifiers from TOPTICA Photonics

Tapered amplifier (TA) diodes 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).

terahertz detectorsS Eterahertz detectors from TOPTICA Photonics

TOPTICA offers receivers for coherent and incoherent terahertz detection. Photoconductive antennas (i.e., coherent detectors) enable phase-sensitive measurements with a high dynamic range in both time-domain and frequency-domain applications. Schottky diodes (incoherent detectors) lend themselves to fast terahertz imaging tasks.

terahertz sourcesS Eterahertz sources from TOPTICA Photonics

TOPTICA’s terahertz sources employ photoconductive antennas, which convert near-infrared laser radiation to terahertz light. TOPTICA offers modules both for time-domain and frequency-domain applications.

All of TOPTICA’s photoconductive antennas come equipped with a silicon lens and SM/PM fiber pigtail, and can be integrated in the terahertz platforms TeraScan, TeraFlash and TeraFlash smart.

Lasers can be used also for a variety of applications to study objects ranging from nanometer scale, via micro- or macroscopic size, even towards galaxies and the universe. For example, artificial guide stars are required to optimize the spatial resolution of Earth-based telescopes. These artificial stars can be created using TOPTICA's guide star laser SodiumStar. This system has been decorated with the Berthold Leibinger innovation price for Laser Research in 2016.
