Toptica awarded major contract for Sodium Guide Star Facility

Orange Laser Guide Star in operation at the Very Large Telescope VLT of ESO, on the top of mountain Cerro Paranal in Chile.

The Very Large Telescope (VLT) of the European Southern Observatory (ESO) at Paranal, Chile, will be equipped with four cw high power Laser Guide Stars on the basis of amplified and frequency-doubled diode laser systems. Narrow band and diffraction-limited laser light sources of more than 20 W exactly on Sodium resonance at 589 nm start a new phase at the European Southern Observatory. Against strong international competitors, TOPTICA won now the final development and supply contract which foresees a deployment of the lasers at the telescope in Sept 2013.

TOPTICA, drawing on its many years of experience in the field of narrow band and tunable diode laser, has joined forces with the Canadian company MPB Communications. A combination of a novel narrow-band Raman fiber amplifier approach at 1178 nm developed by MPBC subsequently is converted to 589 nm by resonantly enhanced frequency-doubling technology. Based on TOPTICA’s scientific product series, conversion efficiencies of more than 80 % have been demonstrated.

Toptica 589nm laser honoured at 2010 CLEO/Laser Focus World Innovation Awards

Toptica's TA / FA SHG pro – Frequency Doubled, High Power Tunable Diode Laser received an honourable mention at the recent 2010 CLEO/Laser Focus World Innovation Awards.

The judges recognised Toptica for "the creation of a tunable, narrow-linewidth, high-power (30 W), 589 nm yellow laser for guide star , spectroscopy, LIDAR, phototherapy, and other visible and near-IR applications."

Discovery Semiconductor showcase Highly Linear Photodiode Instrument

DSI new HLPD Lab Buddy

Discovery Semiconductors Inc., a leading supplier of optical receivers, test instruments and sub-systems, showcased its new Highly Linear Photodiode (HLPD®) Lab Buddy instrument at the recent CLEO/QELS conference in San Jose, CA.

The HLPD® instrument consolidates several years of Discovery’s pioneering work in highly linear photodiode technology.  It combines linear photodiode performance at > 1.5V RF output and 22 GHz of bandwidth with temperature stabilization. Mr. Abhay Joshi, President & CEO of Discovery Semiconductors explained, “As we have progressed towards unprecedented levels of power handling and linearity in photodiodes, stabilizing the device temperature has become essential for reliable performance and even higher linearity.”

Mr. Dan Mohr, Discovery’s Senior Engineer added, “This instrument was developed to deploy Discovery’s HLPD® technology in a flexible laboratory instrument for upcoming applications such as precision photonic oscillators, as well as a characterization standard for a myriad of optoelectronic components.” The new Lab Buddy incorporates front panel controls as well as a remote computer interface to allow seamless integration into various automated test setups.

Ocean Optics Contributes to Gulf Air Quality Monitoring in Wake of Deepwater Horizon Spill

Argos-spectra blog

HR2000 used in Argos portable UV DOAS air monitoring system
Dunedin, Florida (June 14, 2010) – Modular HR2000 spectrometers from Ocean Optics are enabling air quality monitoring in the Gulf of Mexico as part of Argos Scientific’s portable UV DOAS air monitoring system.  Argos Scientific is working in conjunction with Hillsborough County, Florida, to monitor the environmental impact of the Deepwater Horizon oil spill in the Gulf of Mexico.

The project has special significance to Ocean Optics as the company is located on the Gulf side of Florida and its community will be affected in coming months as the oil advances, upsetting both water and air quality.

Ames Photonics: Si Photodiodes and ultrashort laser pulses

Oculus

Recently, Ames Photonics have investigated the feasibility of using silicon photodiodes, like their Oculus USB photodetector, for detecting femtosecond laser pulse energy output.

Silicon photodiodes offer potential advantages for the detection of ultrashort laser pulses. However, until now, no reliable information about saturation energy level, practical energy density and linearity of photodiodes under ultra-short laser pulse exposure has been available in the literature.

The results show that Si photodiode have several advantages compared to other commonly used photosensors, including:

  • Excellent linearity of output current as a function of incident light
  • Very high sensitivity-can typically resolve pJ levels
  • Spectral response from 190 nm to 1100 nm (Si), longer wavelengths with other semiconductor detectors

Edmund Optics Image Rotation Prisms

Half  Penta Prisms

Edmund Optics TECHSPEC® Half Penta Prisms are used to deviate the line of sight by 45° without inverting or reverting the image. The reflecting surface is aluminized and over-coated with Inconel and black paint to increase the prism's efficiency. When combined with a corresponding TECHSPEC® Schmidt Prism, a Pechan Prism pair is formed. The Pechan Prism will invert or revert the image while not deviating the line of sight. The Pechan prism can be placed in converging or diverging light allowing for system size reduction.

Edmund Optics Deformable Mirrors correct spherical aberration

Edmund Optics

Edmund Optics , the premier provider of optical components, has introduced new high performance Deformable Mirrors. These mirrors are the easiest and most convenient tool to correct optical aberrations through wavefront manipulation and control. They are ideal for use in combination with wavefront sensors and real-time control systems in adaptive optics. This particular deformable mirror has 32 radially packed actuators. There is more than 10µm (typically 14µm) of actuator max stroke. They are suited for tabletop applications as well as OEM integration. Priced considerably less than competing products, EO’s Deformable Mirrors are in-stock and available for immediate delivery for fast turnaround and excellent value.

These versatile mirrors will be featured in a special demonstration available for viewing at the EO Booth 1909 during CLEO/QELS 2010, May 18-20, 2010 at the McEnery Convention Center in San Jose, CA. The demonstration will show the integration of a deformable mirror into a PBS-based Twyman-Green Interferometer. By replacing the traditional test surface with a deformable mirror, one can better illustrate the deformations of the mirror’s surface. These small changes in the surface of the mirror create variations in the interferogram. Additionally, this set up highlights how optical noise can be reduced by simply reducing the amount of back reflections in the system.
