Carbon dioxide (CO2) emission lines, suitable for laser operation, span the 9.2 to 10.8 µm wavelength range. Combinations of carbon and oxygen isotopes yield another 17 molecular species - including the popular 12C18O2 and 13C16O2 configurations. With up to 80 lines for each species, these isotopic molecules fill the spectral gaps of the others and extend the spectral range down to 8.9 µm and up to 11.8 µm.
For more than twenty years, Access Laser has provided researchers and industry with application-specific CO2 laser solutions for cutting-edge experiments and products.
CNI Optoelectronics Tech (CNI) offers a nanosecond-pulsed diode laser, with a tunable pulse width of 10 ns to 10 ms (external trigger), good beam profile, and high power stability. Each model of this laser has a single wavelength from 375 to 1310 nm. This laser has an ultra-compact design that can be easily integrated into your instrument. This laser series can be widely used for applications in microelectronics, solar energy, material processing, equipment integration, etc.
In designing a filter solution, the manufacturer takes the values requested by the user and adds additional design margin to account for both functional effects (such as wavelength shift due to angle variation, thermal induced wavelength shift, etc.) and filter manufacturing effects (such as edge steepness, non-uniformity, wavelength targeting — see Iridian’s technical note “Wavelength budgeting for optical filters”).
By providing the true requirements of your system (without padding the numbers), Iridian’s expert designers can produce a filter that will meet expectations for your application and budget.
Thanks to Tony Hallas for sending another amazing image of our universe! This is a picture of the Dumbbell Nebula (M27), located in the constellation Vulpecula. This nebula is about 1360 light years from earth.
This photograph was taken in California using astronomy filters from Chroma Technology. To see more of Tony’s work on his website astrophoto.com, click here.
Researchers have successfully demonstrated a multi-foci, laser-cutting technology for sapphire wafer separation, using Holo/Or multi-focal DOEs. (Sapphire wafers are used for manufacturing LEDs.)
Unlike typical cases where the entire cross-section needs to be scanned with single or multiple passes, this team developed a new separation technique, using only partial thickness scanning, thus increasing process speed. The method exploits the internal reflection at the rough exit surface to decrease the scanning range and increase process efficiency.
The article describing this research is entitled “Multi-Foci Laser Separation of Sapphire Wafers with Partial Thickness Scanning.”

To meet the needs of researchers studying quantum entanglement, ID Quantique provided an array of ID281 superconducting nanowire single-photon detectors. The high efficiency (> 85% at 1550 nm), the high timing precision (< 45 ps FWHM timing jitter), and low detector noise (< 100 Hz dark counts) allowed for the successful characterization of their entanglement sources, the configured two-photon states, and the execution of their quantum-enhanced metrology experiment for fiber core/cladding refractive index differences.
Photonis recently published a paper showing various types of neutron imaging, using a novel laser-driven neutron source. This article shows the crucial role of Photonis’s neutron-sensitive microchannel plates (MCPs) in this research. MCP-based neutron imagers intrinsically have an excellent time resolution, which makes energy-resolved imaging possible. By fast switching of the MCP, one can reject background and select a neutron energy window.
AFMs are very sensitive to background vibration present in the environment, even in laboratory settings. Such vibrations can be mitigated by various vibration isolation solutions. The TS-150 active vibration isolation table from Herzan proves to be superior to passive vibration mitigation schemes.
