Next Generation THz from Toptica: Fast, compact and cost effective

TOPTICA presents new cw THz System with 1.5 µm lasers

At the recent Photonics West exhibition, TOPTICA Photonics presented the most compact frequency-domain terahertz spectrometer built to-date. The system combines TOPTICA’s new TeraBeam, a highly integrated twocolor diode laser, with newly developed InGaAs/InP emitter and detector technology (Fraunhofer Heinrich-Hertz Institute, Berlin, Germany).

The new cw THz system features a fast scan option, which reduces the acquisition times in cw THz spectroscopy by more than two orders of magnitude and acquires a complete THz spectrum (e.g. 50-1200 GHz, sub-GHz resolution) in less than a minute. Thus far, research in the field of frequency-domain (cw) terahertz has largely been carried out with GaAs photomixers, requiring laser wavelengths below 870 nm. Whilst excellent results in terms of bandwidth and signal quality have been obtained, the complexity of the optical source and a variety of non-standard optical components resulted in a price level inadequate for widespread industrial use.

Laser imaging in dense sprays

LaVision Spraymaster

In late 2010, LaVision introduced Structured Laser Illumination Planar Imaging (SLIPI) - a novel technique for laser imaging in dense sprays. Planar laser imaging is widely employed in the field of optical spray diagnostics. However, in many spraying applications or two-phase flows a large amount of light is multiply scattered and the single scattering approximation is no longer valid. This may introduce substantial errors and reduces the number of applications for standard laser imaging techniques. With the new technique of Structured Laser Illumination Planar Imaging (SLIPI) it is possible to suppress multiple scattering and indirect reflections effectively and to enhance image contrast resulting in a much better visualization of break-up and atomization processes in dense sprays. It also enables the feasibility for single-shot and averaged imaging using standard laser systems. From the modulated images SLIPI and conventional results can be extracted and compared.

Edmund Optics Electrically Focus-Tunable Lenses

Edmund Optics Electrically FocusTunable Lenses

Electrically Focus-Tunable Lenses from Edmund Optics offer a single-lens solution for focus and zoom objectives. Applying a control voltage to each compact, plano-convex lens changes their radius. Electrical manipulation of the radius allows for a focal range of +15 to +100mm, providing an adjustable focal length for a variety of purposes and negating the need for a multi-lens system. High refractive or low dispersion materials are offered. The cover glasses are available with VIS or NIR coating. These tunable lenses can replace the functionality of a complete lens kit in laboratory settings, offering the on-demand adaptability needed to avoid the complex mechanical manipulation associated with a multi-lens system. Ideal for researchers and OEMs alike, Focus-Tunable Lenses offer continuous focusability over a specific focal range, allowing the user to custom-tune the lenses for optimum performance.

New Gentec-EO Maestro: Touchscreen Laser Power and Energy Meter

Gentec Maestro


Gentec Electro-Optics have announced the MAESTRO Laser Power & Energy Monitor, their first device with full Touch Screen controls based on a 5.7 inch color LCD screen. The main innovation of this device comes from its ease of use, thanks to an excellent accessibility to all the main functionalities, allowing you to improve your productivity in the lab. Another improvement on the MAESTRO is the data transfer and storage that is now done directly on a USB key. Furthermore, the MAESTRO is also equipped with all the interfaces necessary for an easy and thorough utilization: Ethernet, RS-232, Analog Output, External Trigger and a USB com port for sending serial commands via a PC.

Ocean Optics Announces 2010 Video and Photo Contest Winners


Entries poured in from around the globe
Dunedin, FL (December 10, 2010) – After collecting entries from optical sensing enthusiasts around the world, Ocean Optics has chosen the winners of its annual video and photo contest (www.oceanphotochallenge.com). Winner of the $2,500 Grand Prize in the video category, San Diego State University Student Cory Stinson, was chosen for his entry Into the Ocean of Optics and Lasers. In the photo category, Jeff Van Camp was awarded the $1,000 Grand Prize for his photo series A Quick Look Over the Shoulder.

Stinson’s winning video highlights the capabilities of an Ocean Optics spectrometer with real time experimental footage and 3D computer animation. The experimental setup measures the spectrum of a laser output in real time while the majority of the laser beam that passes directly through a beam splitter is incident on a CCD sensor to look at spatial modulation.

Thorlabs Swept Source OCT Systems

Schematic of Thorlabs Swept OCT Source

Figure 1. Schematic of OCM1300SS Swept Source OCT Microscope: swept laser source (SS), fiber coupler (FC), polarization controller (PC), circulator (CIR), collimator (C), variable attenuator (VA), mirror (M), balanced detector (BD), data acquisition board (DAQ), XY scanner driver (SD), CCD camera (CCD), objective (OBJ), microscope (MS), analog output (AO), aiming laser (AL). The Mach-Zehnder interferometer (MZI), which is built in the swept light source, provides the frequency clock signal for the laser.

The Thorlabs Swept Source OCT is a frequency domain OCT technique that measures the magnitude and time delay of reflected light in order to construct depth profiles (A-scans) in the sample being imaged. Adjacent A-scans are then taken and all the images combined to create a 3D image. The design integrates a broadband, high-speed swept laser and a fiber-based Michelson interferometer with a balanced detection scheme. The multifunctional system includes an integrated CCD camera which provides simultaneous en-face and cross-sectional OCT imaging of the sample. The system includes a handheld probe that can be mounted onto an adjustable XYZ stage for a more stable imaging platform.

Phaseview: Beamwave

Phaseview Beamwave

Instant Laser Beam Profiler: Entire Beam Visualization & Wavefront Analysis in One Shot

With no moving parts or additional accessories, Phaseview 's BeamWave performs real-time measurements of all critical laser beam characteristics including intensity distribution, wavefront and beam propagation parameters.

Thanks to its capability to measure simultaneously intensity and phase data at ultra high resolution, beam shape and intensity distribution can be measured at any distance from the device’s measurement location without moving parts. All critical data for laser beam monitoring such as power distribution and beam propagation parameters can be measured without additional tools.

BeamWave® provides high resolution wavefront data which allow laser beam analysis in its all dimensions. From the wavefront data, Zernike analysis is performed; beam’s astigmatism, other low and high order aberrations can precisely measured.

BeamWave® provides comprehensive one-shot measurements of the laser beam: beam propagation parameters such as M², divergence, tilt, Raileigh range, beam power characteristics in any XY plane along the propagation direction of the beam, thus providing an instant picture of laser beam behavior along the propagation axis.
