Part of a project funded by u-Care aims to develop tunable, ultrashort pulses of light in the vacuum ultraviolet (VUV, 100โ200 nm) and middle ultraviolet aka deep ultraviolet (MUV/DUV, 200โ300 nm) for use in ultrafast spectroscopy, technology, and healthcare applications. The team exploited a phenomenon known as resonant dispersive wave emission using gas-filled hollow-core capillary fibers to achieve this. To download theย paper, clickย here. Such compact tabletop systems can be realized using industrialized pump lasers such as PHAROS system fromย Light Conversion. | |

CNI Optoelectronics (CNI)ย introduces the photoelectric-integratedย MDL-XL laser series. The features are designed to ensure easy integration, high reliability, adjustable focus, good environmental adaptability, and more. The user simply needs to provide a digital modulation signal to synchronize the enable time and disable time of the laser emission. The MDL-XL series module provides stable performance and high reliability. Features of the MDL-XL include:

A research group atย Umeรฅ Universityย produced a laser source with < 4 fs pulse duration and > 5 TW peak power. This device is now the most powerful sub-4-fs laser system in the world. The front-end of the system containsย Light Conversionโs PHAROS andย ORPHEUS-OPCPA. The paper detailing this work is entitled, โUtilizing the temporal superresolution approach in an optical parametric synthesizer to generate multi-TW sub-4-fs light pulses,โ is available on line in the journal Optics Express. |

As a leading manufacturer of optical components for high laser-induced damage threshold (LIDT) and ultrafast pulse laser applications,ย Manx Precision Optics (MPO)ย constantly expands their product range to offer customers the latest, state-of-the-art components. MPO has developed a line of broadband, low dispersion mirrors (TTMH, TTMP, TTW, TTB and TTS) to provide suitable solutions for all customer applications. | |
Iridian Spectral Technologiesย offers all critical filter types for your Raman spectroscopy needs. For the critical spectral separation and detection of Raman scattering at both longer and shorter wavelengths simultaneously, Ramanย notch filtersย are a suitable choice. Notch filters block a narrow wavelength range in between the passband regions. They block the laser line and enable high transmittance of scattered light at both the shorter and longer wavelengths for Raman spectroscopy analysis. If the detection of Raman photons is limited to Stokes scattering at longer wavelengths then the light source, Ramanย edge filtersย (longpass) andย dichroic long pass filtersย are applicable. These types of filters isolate the Raman signal band at a specific edge wavelength. Further, dichroic filters direct source laser light towards the sample, while a scattered Raman signal from the other direction passes the filter and hits the detector. Raman edge filters are also available as short pass filters to selectively enable anti-Stokes Raman spectroscopy at short wavelengths. | |
Aย Flexishaper, developed byย Holo/Orย in 2020, includes a pair of diffractive optical elements (DOEs) generating a central spot and a concentric ring of laser light. By adjusting the relative rotation angle between the two DOEs, the spatial power distribution between core and ring can be freely adjusted. Properties such as the ring diameter are predetermined by the design of the DOEs. The application of DOE-based beam shaping improves the high-speed welding of foils for bipolar plates used in the fuel cells for electric vehicles. For more information,ย contact Holo/Or. | |
Manx Precision Optics has (MPO)ย released their latest technical note (TN2022-03), which is a white paper entitled โThe Cleaning of Optics: An Overview.โ This paper provides an overview of the reasons why cleanliness is so important for optics. It explains the ISO standards for cleanliness related to optics production and introduces Manxโs methods to adhere to these standards. | |
In the past decade, we all became more aware of the need for green sources of energy, such as solar and wind power, to replace polluting sources of energy, such as fossil fuel and coal. One of the great hopes for this transition is the utilization of the sunโs radiation for production of electricity, solar power. The way to utilize solar power is through solar panels with photovoltaic cells.ย Top hat beam shapersย from Holo/Or have enabled a revolution in the production of solar panels and the optimization of the solar power collection process.

Thank you to Tony Hallas for capturing this amazing image of Messier 82! Also known as M82, this starburst galaxy is located in the constellation Ursa Major, and is about 12 million light years away. This photo was taken with Chroma Technologyโsย LRGBย andย H-alphaย astronomy filters. Chroma Technologyย manufactures the highest qualityย astronomy filtersย with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations. All primary filter coatings are applied on the front surface and anti-reflection coatings on the rear surface to prevent ghosting and to maximize transmission.
