xyz-piezo scanner gives 25 pm resolution
Physik Instrumente (PI) will exhibit its new PicoCube high-resolution positioning and scanning system. The P-363 PicoCube, together with its ultra-low noise E-536 driver / controller, provide higher resolution and positional stability than previous multi-axis scanning stages, the manufacturer claims. The P-363 and controller provide 25 pm resolution and a PID response. Aplications include: atomic force microscopy, scanning probe microscopy and nanomanipulation, biotechnology, nanotechnology, nano-imprint, semiconductor and data storage, and test equipment. PicoCube systems are designed to overcome the limitations of open-loop piezo-tube based scanners which provide high resolution motion but poor linearity and trajectory guidance.

Fber-optic connector cleaver
Te Comet is a laser cleaver from manufacturer Sagitta. It is a bench-top module that utilizes a non-contact laser system to cleave optical fiber and remove the epoxy bead on optical connectors. The cleaver is designed for mass-production in fiber-optic termination shops both to increase the yield during termination and cut the cost of polishing material subsequently. The system allows consistent cleave height and does not require an operator to rely on epoxy bead size or special cleaving skills. It eliminates scribe blade wear and epoxy removal steps, resulting in lower production costs. Adapters for all type of 1.25 mm and 2.5 mm simplex connectors are available.

Low-loss fiber splicer
The GPX-3400 glass processing station in combination with the LDC-200 large diameter fiber cleaver is available from Vytran and distributed by AMS TEchnologies. The GPX platform makes use of Vytran's patented filament fusion technology which provides a stable high-temperature source to control glass processing conditions. Its design allows for fabrication of splices, tapers, mode adapters, N.A. converters, end-caps, couplers and combiners with optical fibers ranging from 125 µm up to 1.5 µm in diameter. As a splicer it can produce low loss splices for multimode and singlemode fibers. Variants of the GPX-3000 are designed for the particular needs of producing fiber-optic components and splices for high power applications.

Tighter, brighter spot
Blue Sky Research's CircuLasers, which offer both higher powers and various wavelengths, are produced by mounting the proprietary µLens directly in front of a diode chip emitter. This transforms the elliptical output beam of a standard laser diode into a circular beam. The lens profile compresses the fast-axis of the beam down to the divergence angle of the slow axis, thus converting the beam's elliptical shape into a gradually diverging, circular cross-section. A circular beam is suited to a wide range of applications including analytical instrumentation, data storage and laser scanning and printing. The µLens provides high power efficiency; its high entrance NA (~0.7) captures almost all of the output of a diode. CircuLaser diodes are suitable building blocks for modules and fiber-coupled packages.

'Supercontinuum' white broadband sources
Koheras is introducing an addition to its broadband white light SuperK product family called the SuperK Compact. It is designed to be a maintenance-free turnkey system covering the visible-to-near IR spectrum with "exceptional" beam characteristics. It covers the range between 500 and 1750 nm with an output power of 100 mW and a minimum power density of -20 dBm/nm. The pulsed system has a repetition rate of 25 kHz and pulse lengths of 1-2 ns. The latest generation SuperK Compact supersedes the preceding SuperK Red model and is availble in a more compact design. Its connectorized output allows it to be connected to any component, fiber or optical system under test. The SuperK Compact also suits applications such as optical coherence tomography (OCT), bio-analysis, and white light interferometry.

400 MHz photoreceiver
The HCA-S-400M series of 400 MHz photoreceivers, the latest additions to Femto's range, offer a bandwidth of DC to 400 MHz for fast optical measurement with rise times as low as 1 ns. Two models with either a built-in silicon or InGaAs photodiode cover the spectral range from 320 to 1700 nm. The photoreceivers incorporate an HF amplifier with low noise and a gain of 5x10³ V/A for rapid and sensitive measurement of signals with an optical power down to 4 µW. Integrated offset circuitry allows the compensation of the photodiode dark current and of unwanted background signals overlaying the actual signal of interest. The signal is fully DC-coupled to allow accurate measurement of pulses and digital signals without signal overshoots and baseline shifts. As well as models with a "free space" input, alternative FC or SMA fiber inputs are also available for measurements on fiber optic systems. Typical applications are in spectroscopy, laser characterization, pulse and transient measurements, testing of communication equipment and industrial sensing.

VCSEL reflective sensors
Reflective sensors offer a high quality beam profile, higher signal to noise ratio, speed and reliability compared with edge emitting lasers and LED solutions. The HVS6003-001 is a hermetic TO can reflective sensor with an integral lens and an operating temperature range of -40 to 85 °C. The laser emits a narrow, coherent output at 850 nm, producing a spot at ~15 mm from the package. Reflected light is detected by the integral phototransistor, with 1 mW optical output power from the VCSEL. The SNR of the device is >20dB, unheard of in other reflective sensor solutions. The HVS6003-002 is a leadframe packaged sensor utilizing the same VCSEL and phototransistor as the 001 but packaged in a low-cost, surface-mountable package. The 002 easily detects targets beyond the range of LED-based sensors at a fraction of the drive current and at higher speeds.

Sub-surface image capture and display
Michelson Diagnostics (MD) will be demonstrating real-time sub-surface image capture and display at a resolution greater than 10 µm. This is achieved by the EX1301 OCT microscope. The demonstration will be hosted by MD's supplier Santec Europe in the UK Pavilion. The EX1301 OCT Microscope is suitable for use by research scientists needing to image below the surface of tissue samples, non-invasively and at high resolution. MD's optical coherence tomography (OCT) equipment, which employ Santec swept-source lasers, are focused on cancer diagnosis and surgery. Two of MD's instruments are already undergoing testing at two leading teaching hospitals in the UK. "Our experience in developing reliable imaging products supports our aim of offering the best available OCT imaging to customers," said Gordon McKenzie, MD's applications director. "We are keen to get feedback from visitors to Laser on what they are looking for from the next generation of in vivo OCT systems."

Optical design software
New features have been added to Liekki's Application Designer v4.0 (LAD) software, a versatile design tool for high power applications. LAD simulates and optimizes fiber amplifiers, amplifying spontaneous emission sources, and fiber laser systems. The package is based on algorithms that account for all reflections in a system. It can also simulate large mode area and highly doped fibers. LAD v4.0, which will be formally launched in October 2007, is an upgrade of LAD v3.3 and it offers several new features. It will include wizards that allow the creation of designs and simulations with a Windows-based, step-by-step approach. The wizards will be available for erbium- and ytterbium-doped fiber amplifiers, ytterbium-doped fiber lasers (YDFL) and ASE sources. More wizards can be added on request. LAD v4.0 can optimize a design parameter for a specified target. For instance, obtaining the optimum fiber length for a given gain. The new package will also include a multimode analysis of coiled fibers that allows to calculate the propagation effects of higher order modes in coiled fibers.
