In a recent article, Alexander Brodsky and Natan Kaplan of Holo/Or present “a new method for simulating and optimizing both single and multi-mode lasers in Zemax™ by applying a scattering model.” The abstract of the article follows: By default, optical systems are usually designed for single mode lasers. Nonetheless, many industrial lasers have M2 in … Continue reading
Holo/Or now offers an expanded selection of ZnSe Diffractive Axicons, suitable for ring shaping and Bessel beam generation C02 laser wavelengths. Unlike regular axicons, Holo-Or’s diffractive axicons have no rounded tip area in the center and have absolute divergence angle accuracy, even at very low angles. This gives them the unparalleled shaping quality required for demanding, … Continue reading
For certain applications the intensity distribution along the focal axis is the most important parameter. Among these applications are glass drilling, glass cutting, cytometry, microscopy, and inspection. Holo/Or’s Beam Foci elements are used for such applications, to shape or split the energy along the focal axis. To support customers who are integrating these Foci elements, … Continue reading
Transforming the beam of a highly multi-mode laser into a narrow annular shape with almost single mode diffraction-limited ring width is a potentially useful technique for certain material processing applications, such as drilling and cutting. Holo/Or has published an experimental demonstration of our unique diffractive method of doing this transformation. To read a new article … Continue reading
Holo/Or has ongoing cooperation with international research institutes on developing state of the art industrial laser technologies. During the Tailorweld project, we developed custom C Shape beam shaper elements that improve the welding process. It was found that the C Shape intensity distribution has advantages in the width/depth ratio, reducing oxidation and eliminating hot cracking … Continue reading
Many laser-based systems, especially in the life sciences, projection and projection mapping fields, require the use of more than a single wavelength, high power laser on the same optical path to achieve the desired functionality. To meet this need, Holo/Or has developed the high-power Broadband Diffuser (BD). The BD is a micro-refractive diffuser, specially designed … Continue reading
Many applications in the solar panels and microelectronic industries require parallel ablation or scribing of lines on a flat substrate, such as scribing of electrodes or copper removal. These sorts of applications often employ Holo/Or’s Multi-Spot Beam Splitter DOE to create the spots used for the parallel writing, along with a scanner. Often, a large … Continue reading
The R&D physicist at Holo/Or just published a new article about M2 transformation, useful for industrial laser material processing applications. The article discusses a laser M2 transformation system in polar coordinates, where a multimode laser beam is transformed into a ring-shaped beam with close to single mode beam quality in radial coordinate (ring thickness), and … Continue reading
Holo/Or is participating in a new HO2020 framework European laser surface processing project, called PROMETHEUS. This project pushes the boundaries of laser surface texturing technology to a new level! Within this project, Holo/Or will develop a novel diffractive-based M2 transformation module for high power, short pulse lasers to enable the precise periodic texturing of functional … Continue reading
Laser glass cutting with ultra-short IR pulses is fast becoming a key technique for high throughput glass processing. Cutting of thick glass (> 500 µm) using this technique possesses unique challenges, as the laser energy needs to be both focused to a tight spot and spread evenly throughout the depth of the glass. To help … Continue reading
