Toptica Product Focus: Continuously Tunable Lasers

TOPTICA Tuesday 20170530 400x650 CTL

Wide mode-hop-free tuning is important for many exciting applications: for example resonant excitation of small structures like quantum dots and micro-cavities as well as molecular spectroscopy or components testing. TOPTICA is specialized in tunable diode lasers with excellent precision, reliability and ease-of-use.

For example, TOPTICA’s CTL – continuously tunable laser – enables mode-hop-free tuning of up to 110 nm at several central wavelengths. Wide scans can be performed with highest resolution and narrow linewidth, and CTL features high absolute and relative wavelength accuracy as well as high power.

In combination with its fully digital controller DLC pro, the CTL laser is easy to use and operate via touch-screen and knobs as well as via remote PC GUI and command language. The low noise and drift levels of the controller make the CTL series even more stable and lowest-noise.

Raptor releases new OWL 320 High Speed VIS-SWIR camera

OWL 320 HS VIS SWIR

Raptor Photonics has added another member to its growing family of InGaAs based cameras. The OWL 320 High Speed VIS-SWIR features a state of the art high sensitivity InGaAs FPA sensor with a resolution of 320 x 256, and a pixel pitch of 30µm x 30µm. This camera now offers VIS-SWIR sensitivity from 400nm to 1700nm. This will be in addition to the SWIR version of the camera, running from 900nm to 1700nm.

The OWL 320 High-Speed VIS-SWIR series offers unsurpassed speeds of 346 Hz for ultrafast applications with high sensitivity response allowing exposure time from 500ns to 5 seconds. Further details available here.

New Becker+Hickl ultra-fast detectors improve NADH FLIM

 workshopnadh04 a1a2 2 8 txt comp80

Image: NADH Lifetime image, amplitude-weighted lifetime of double-exponential fit

NADH FLIM is based on the separation of the fluorescence decay components of the bound and the unbound fraction of NAD(P)H. The amplitudes and the decay times of the components are used to derive information on the metabolic state of the cells or the tissue. The separation of the decay components and the accuracy of the amplitudes and lifetimes improves substantially by using the ultra-fast HPM-100-06 and HPM-100-07 hybrid detectors. The IRF width in combination with the SPC-150N and SPC-150NX TCSPC modules is less than 20 ps. An IRF this fast does not interfere with the fluorescence decay. The usual deconvolution process in the data analysis virtually becomes a simple curve fitting, and the decay parameters are obtained at unprecendented accuracy.

nanoplus DFB interband cascade laser facilitates new TDLAS applications in mid-infrared

 csm nanoplus TO66 d79118cdcf

nanoplus offers a DFB interband cascade laser (ICL) at any target wavelength in the mid-infrared (MIR) between 3 μm and 6 μm. The device operates in continuous wave (cw) mode around room temperature. Specifications and behavior are very comparable to a nanoplus laser at lower wavelengths. When you set up an ICL-based analyzer, you can, hence, transfer the engineering knowledge you have gained from building short-wavelength gas sensors.

The nanoplus DFB ICL opens tunable laser absorption spectroscopy (TLAS) for novel MIR applications in industrial gas sensing.

In the 3 μm to 6 μm wavelength window, now covered by interband cascade lasers, many industrially relevant trace gases have their strongest absorption bands. They show absorption strengths that are several orders of magnitude higher than those in other infrared (IR) areas. This concerns prevalent molecules such as carbon dioxide (CO2), nitric oxide (NO) or water (H2O). Most hydrocarbons, e. g. methane, equally locate their topmost absorbing features at these ICL wavelengths.

A novel 1p-SLIPI approach simplifies stray-light free instantaneous imaging in dense sprays

 1 p SLIPI

LaVision presents the latest innovation for stray light suppression in sprays and two-phase flows

Structured Laser Illumination Planar Imaging (SLIPI) is an established technique in planar laser imaging to remove imaging artifacts arising from higher order scattering in 2-phase fluids, such as sprays. Developed with their cooperation partners from Lund University, LaVision now provides a remarkable simplification of SLIPI with the new single pulse SLIPI approach.

Instantaneous 1p-SLIPI This novel technique reveals fully time resolved spray images from single-shot recordings. Single pulse SLIPI (1p-SLIPI) is the simplest way of rejecting stray-light in dense media.The instantaneous double pulse 2p-SLIPI and the phase-scanning and time-averaging 3p-SLIPI offer solutions to customers with higher demands on spatial resolution or for more complex spray imaging techniques like LIF/Mie.

The SLIPI optics is designed to start with the most simple 1p-SLIPI approach and can be upgraded with rising demands. The SLIPI base module covers all requirements for 1p-SLIPI. Two add-on modules for the SLIPI optics for 2p- and 3p-SLIPI allow to upgrade to one or both of the more advanced techniques. Read more about SLIPI here.

Laser Quantum: The gem vs. world-class production

Over the past months, Laser Quantum have tested their gem laser under extreme conditions. Away from the laboratory, we have subjected this laser to being driven over by a Range Rover; being dropped from 20 metres; being frozen in a block of ice; being buried in sand and hammered with a wacker plate and being spun in a tumble dryer. The gem has survived every single test. In our final video of the series, we take you behind the scenes of our world-class production facilities to demonstrate the real test processes each of our lasers go through in order to meet our meticulous high standards. It is these high standards which have enabled the gem laser to survive the extreme testing from our previous videos. To gain an insight into our laboratories and our industry-leading testing procedure, watch the gem vs. world-class production now!
