PRODUCT UPDATE LASERS
High volume production lasers
Lumentum’s Corelight YLE fibre laser engines are now available in production
volumes. Offered in single-module 2kW and 3kW systems and multi-module 4kW, 6kW and 9kW systems, these cost-effective and configurable fibre laser systems are suitable for a wide variety of cutting, welding, and material deposition applications. Corelight’s excellent beam characteristics enable high-quality and high-speed cutting of mild steel, stainless steel, aluminium, copper, brass and many other materials. Corelight products meet high-reliability
standards critical for high-volume industrial environments.
The Lumentum 200W fibre-coupled diode pump laser, the ST2, is also now in high-volume production. The ST2 recently completed a 10,000-hour reliability test ensuring endurance and power stability to withstand prolonged use in harsh manufacturing settings.
In addition to the ST2, Lumentum has a full portfolio of advanced fibre-coupled devices based on the low-cost L4 platform.

DSH-355-40 UV laser
Photonics Industries has increased the pulse energy of its DSH series UV
nanosecond laser to 1mJ. The DSH-355-40 laser is a compact, nanosecond 355nm laser using intracavity UV generation with pulses triggered on demand. It has up to 50W of output power. With the DSH-355-40 laser, industrial
micromachining customers can process materials at a much quicker, more efficient rate, expediting their manufacturing processes with a small amount of cost increase to yield two times or more throughput for a large number of
OPTICS Laser optics videos
Edmund Optics has released the Laser Optics Lab, a video series that helps customers better understand laser optics technology and its applications.
The first five videos, each Multifocal lenses
Diffractive multifocal lenses (MF) are widely used for glass cutting applications. Holo/ Or has developed a tailored focusing module for glass cutting applications, integrating multifocal lenses with a focusing objective. Unlike refractive solutions, Holo/Or’s diffractive MF focus module works for single, as well as multi-mode lasers, and maintains diffraction- limited spot size at all foci.

approximately three minutes or less, explain the fundamentals of laser optics, including specifications, product types and coating methods. These videos are designed to guide viewers around key laser optics
Freeform beam shaping laser optics
II‐VI has introduced its freeform beam shaping laser
optics for fibre and direct diode laser applications. The company’s freeform diamond turning capabilities deliver custom high-power laser optics with
concepts, helping them choose the best product to integrate into their system or project.
Laser Optics Lab begins with five stand-alone video segments. The introduction gives an overview of laser technology, examines the physics behind how lasers work and showcases different laser types. The back reflections segment explains them, why they occur and how to prevent them.
The specifications for selecting a
laser segment discusses wavelength, coherence length, beam divergence, and Rayleigh range. The beam expander configurations and design segment introduces the uses of beam expanders and considers their differing designs and how they work. Finally, the coatings section explores the different types used for laser optics and explains their benefits. More videos will appear this year.

applications. Also, a pulse energy of 1mJ enables applications that were not possible in the past. The new UV nanosecond laser also typically
provides one per cent P-P stability with typical beam quality of M2 1.1. It has a small footprint and low power consumption. The single-box design simplifies installation by removing the need to manage a separate controller or power supply box and umbilical cable. Eliminating the driver and umbilical, the new DSH-355-40 is so lightweight and robust that it can be vertically mounted on a gantry for robotic applications.

precise surface finish for use in advanced laser processing heads. II‐VI’s Bessel focus lenses, for example, enable customers to engineer beams with elongated depth of focus that greatly improve the efficiency of laser processing heads. The firm offers a broad range of freeform beam shaping
laser optics including Bessel focus lenses, facetted integrators, vortex lenses, flat-top converters, biconic lenses, axicons and dual focus lenses. It also offers debris windows and turnkey capabilities in optical design, fabrication, thin film coatings and metrology.
