New Compact Diode-pumped Nd:YAG Laser
Quantel/Lumibird is pleased to announce the release of the new Shrike compact diode-pumped Nd:YAG laser, which is capable of delvering an energy of 130mJ at 1064nm, powered by a simple 24V power supply and integrated into an ultra-compact package.
The Shrike benefits from all the features that have made the Centurion+ and Viron series laser systems so successful: embedded electronics in the laser head and a sealed (IP66), vibration-tested (MIL-STD-810H) structure that adapts to the most extreme environments. Combined with excellent optical specifications, these features make the Shrike an outstanding laser.
This new pulsed Nd:YAG laser demonstrates once again Lumibird's commitment to offer benchmark tools that incorporate the latest innovations to meet the ever evolving needs of its customers.

Practical Considerations for Reliable Characteriation of Electrical Devices
Date: Friday 13 October 2023
Time: 3am NZDT | 1am AEDT | Midnight AEST | 10pm AWST (Thurs 12th)
Various steps go into accurately characterising new devices, especially when measuring electrical signals, voltage, and current.
This webinar will cover these steps, discussing what’s necessary to ensure high-quality and repeatable measurements — particularly when characterising at cryogenic temperatures.
Lake Shore's Jason Chonko, the webinar's presenter, will discuss ways to:
- Reduce the impact of noise, self-heating, and other parasitics
- Simplify connections to the device under test, including ground connections
- Ensure simultaneous measurements when testing multiple samples
- Minimize ground loops and crosstalk on instrument cabling
By attending this webinar, you will learn:
- The importance of when to use shielding and guarding on fixturing and cabling
- How to identify and deal with common sources of environmental noise
- Single-ended vs. differential measurement techniques
- How to choose between a voltage or current source depending on the resistance of the device measured
- A new approach to performing DC and lock-in measurements
About the speaker:
Jason Chonko is a Business Development Manager with Lake Shore Cryotronics. A 1998 graduate of Kent State University with a BSci in Physics, he started his career as a Lab Technician at the university’s Liquid Crystal Institute, then worked at several optical startups as a Staff Engineer dealing with the challenges of research and design. Most of his 25-plus years in the industry have been spent as an Applications Engineer and marketer for several general-purpose test and measurement companies, with the goal of always helping customers get the most out of their instrumentation. With Lake Shore, he specializes in electrical device characterisation systems, often performing technical analysis of customer applications to aid in product selection.
EDAX Webinar : Introduction to Electron Backscatter Diffraction (EBSD)
Date: Friday 29 September 2023
Time: 3am NZST | 1am AEST | 11pm AWST (Thurs 28th)
While electron backscatter diffraction (EBSD) was discovered in 1928 by Kikuchi, it wasn’t until the full automation of the technique in 1991 that the technique’s utility for characterising microstructure was truly realised. EBSD is a scanning electron microscopy (SEM)-based technique that provides a practical means of quantifying and visualising the crystallographic aspects of a polycrystalline material’s microstructure on a point-specific basis. EBSD systems are now found on SEMs in materials characterisation labs worldwide. This webinar will introduce the EBSD technique, including a discussion on the interplay between diffraction physics and crystallography. This will be followed by an introduction to EBSD applications in materials science, engineering, and the earth sciences.
Presenter: Dr Stuart Wright, Senior Scientist, Gatan/EDAX

The Route to Better EBSD Results: New Detector Technology, Improved Indexing Algorithms, and Sample Preparation
Date: 27 June 2023
Time: 11:30am NZST, 9:30am AEST, 7:30am AWST
Abstract:
Electron Backscatter Diffraction (EBSD) has become a well-accepted microanalysis technique used for the routine characterisation of crystalline materials. Recent developments in hardware and software have extended the capability of this technique. Direct detectors, in contrast with phosphor-screen-based indirect detectors, provide higher sensitivity, higher information fidelity, and improved pattern quality. The application of dynamic diffraction-based forward model matching, termed spherical indexing, to determine crystallographic orientation and phase has improved indexing rates compared with traditional Hough-based indexing and opened new routes for resolving pseudosymmetry issues and better orientation precision. All this technology though requires a usable EBSD pattern, which in turn requires adequate specimen preparation. In this presentation, advances and examples of direct detection, spherical indexing, and sample preparation will be discussed, with examples showing improved EBSD characterisation capability enabled by these advances.
Bio:
Matt Nowell is the EBSD Product Manager at EDAX and has a passion for EBSD and microstructural characterisation. Matt joined TexSEM Labs (TSL) upon graduation from the University of Utah in 1995 with a degree in Materials Science and Engineering. At TSL, he was part of the team that pioneered the development and commercialisation of EBSD and OIM. After EDAX acquired TSL in 1999, he joined the applications group to help continue to develop EBSD as a technique, and integrate structural information with chemical information collected using EDS.
Within EDAX, Matt has held several roles, including product management, business development, customer and technical support, engineering, and applications support and development. Matt has published over 100 papers in a variety of application areas. He greatly enjoys the opportunity to interact with scientists, engineers, and microscopists to help expand the role that EBSD plays in materials characterisation. In his spare time, Matt enjoys playing golf and pondering if changing the texture of his clubs will affect his final score.

Next Generation, Ultralow Cost UV Lasers
Coherent, a leader in advanced laser processing solutions, today announced the introduction of its next-generation ultralow-cost Matrix nanosecond pulsed UV lasers for high-contrast marking applications in consumer goods, industrial electronics, home appliances, and packaging.
The increasing adoption of ecofriendly non-contact laser marking in consumer devices and packaging is driving the demand for cost-effective UV lasers that enable permanent, damage-free marking. The new Matrix UV lasers from Coherent are diode-pumped solid-state lasers that provide superior marking quality at half the entry price of existing solutions.
The new Matrix lasers are available with 5 W and 10 W output power and operate at a pulse repetition rate ranging from 50 kHz to 300 kHz. The lasers can achieve more than 15,000 hours of maintenance-free operation, enabling reliable high-volume production. The Matrix lasers can output up to 200 µJ of pulse energy at 355 nm for the most demanding applications and are based on Coherent’s field-proven UV technology.
