โ‚Lasers

Theย Access Laserย AL50Q is a compact,​​ RF-excited, INVAR-stabilized, fully sealed,​​ CO2ย waveguide laser that is Q-switched with an acoustic-optical modulator (AOM). This results in outstanding pulse characteristics with high peak powers of 2.5 kW, 200 ns pulse widths, and frequencies up to 60 kHz.​​ 

Controlled matching of RF-excitation and Q-switching, so-called super pulsing (SP), enables peak powers up to 10 kW at frequencies of several hundred hertz.

Processing (cutting or micro-structuring) tempered or non-tempered, flexible or thick glass with high precision can be a challenging task. Mesh glass wafers and wafers for wafer-level-packaging (WLP) require various shapes of through-holes with high aspect ratio channels in the same wafer. Femtosecond lasers are perfect for both selective laser etching (SLE) and 5-axis drilling heads.

Theย CARBIDEย laser fromย Light Conversionย is a common choice for SLE and glass drilling applications.ย

A team at the University of Oxford, Department of Engineering Science have developed sapphire fiber sensors that can withstand extreme temperatures. These sensors have the potential to increase efficiency and reduce emissions in aerospace and power generation.

Light Conversionย is very proud to have supplied theย PHAROSย femtosecond laser for this research. This industrialized femtosecond laser was used to inscribe novel structures into optical fibers to sense parameters,​​ such as temperature, pressure, and strain.

Image of incident light to optical filter

A post byย Iridian Spectral Technologiesย highlights the important filter types and characteristics to define before manufacturing a filter. These characteristics include:

  • Operational wavelength​​ 

  • Angle of incidence

  • Polarization

  • Surface finish/quality

  • Surface shape and wavefront error

  • Substrate and filter dimensions

  • Clarity of aperture

  • Orientation

Here is another fantastic image from Terry Hancock! The Seagull Nebula (IC2177 and NGC 2327) is located in the constellations of Monoceros and Canis Major, lying at a distance of 3,600 light-years from Earth. This image was taken at Grand Mesa Observatory in Colorado over the course of 4 days with a total acquisition time of 14.6 hours, using Chroma narrowband filters.

Chroma Technologyย manufactures the highest qualityย filtersย andย filter sets, includingย astronomy filtersย with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations.

In aย videoย from SPIE DCS2022, Jason Palidwar (Product Group Manager โ€“ Aerospace and Specialty Optics ofย Iridian Spectral Technologies) discusses Iridianโ€™s optical filters for remote sensing. These include components for earth observation (EO), IR gas sensing, and LiDAR. This video discusses how these filters provide โ€œMore Signal and Less Backgroundโ€ to customersโ€™ instruments and systems.

 

โ‚Light Sources

ISTEQย introduces their latest products in the EUV light source โ€”ย 13.5 nm TEUS (S100, S200 and S400) product line. These devices are based on laser-produced plasma (LPP) with extremely high brightness, low debris, and a high duty cycle.

Right now this is the only LPP EUV light source available worldwide for mask inspections and other critical EUVL testing applications.

The LPP EUV source is based on a fast rotating, liquid metal target. A novel LPP target with conventional debris mitigation techniques has resulted in an ultimate solution for a clean photon EUV source.
