Underwater Optical System Images Seafloor at Microscale
An underwater computer with an interface to a microscopic imaging unit is enabling scientists to non-invasively image seafloor environments and organisms in situ at nearly µM resolution. The system, called the Benthic Underwater Microscope (BUM), will help scientists better understand the dynamic ecological processes taking place underwater on a microscopic scale.

Microscopy Uncovers Potential Way to Improve Solar Cell Efficiency
Advanced microscopy techniques have been used to show that adding the optimum amount of selenium (Se) may help increase efficiency in cadium (Cd)- and tellurium (Te)-based solar cells from the current approximate 22 percent to levels approaching the theoretical limit of 30 to 33 percent. To study the effect of Se content on the photoactive properties of bandgap-graded CdTe cells, researchers at Oak Ridge National Laboratory (ORNL) used a combination of techniques including atom probe tomography, transmission electron microscopy and electron beam-induced current.

Metamaterial Switches States in Response to Light
A metamaterial has been designed with a switchable metasurface that allows it to either block or transmit light waves in response to light pulses. Developed by researchers at the University of Southampton, the optically switchable metamaterial uses the phase-change medium germanium antimony telluride (GST) to change properties, a capability that may be useful for a range of optical devices.

Lasers May Remove Space Debris Using Novel Approach
Laser ablation can be used to remove interference in satellite communications by pushing pieces of space debris into the Earth’s atmosphere, where the debris is destroyed. A novel approach to laser ablation of space objects focuses on a secondary effect of laser-induced damage, which is not immediately apparent in experiments on Earth but becomes relevant in the weightlessness of space: when laser-induced material ablation occurs, the recoil of the ablation plume yields momentum transfer to the target.

Magnetic Materials Drive Up Power of Compact Q-Switched Laser
A submillimeter-thick film with magnetic microdomains has been used to control a Q-switched laser, increasing its pulse power by 1,000 times. The laser, developed using a 190-µ-thick garnet film with labyrinth-shaped magnetic domains, may be the first magneto-optic (MO) Q-switched laser developed using thin magnetic garnets.

DBR Laser with Beam Correction
Photodigm Inc.
Photodigm DBR lasers are now available with integrated beam correction. A Virtual Point Source (VPS) microlens inside the package corrects astigmatism and reduces fast axis divergence resulting in a user friendly near circular beam. This increases coupling efficiency/transmitted power and improves performance for...
