New Diffractive Lens Array Diffusers from Holo/Or

Various laser applications require precise and efficient diffusers at low angles. Holo/Or’s new diffractive lens array diffusers have total (<10-5) ROC accuracy and feature diffraction efficiencies of ~ 95%, with no dead zones between the lenses. Due to their thinness and diffractive nature, they are not affected by thermal lensing and other temperature-related effects and … Continue reading

Glass Cutting with Ultra-Short IR Laser Pulses

Laser glass cutting with ultra-short IR pulses is now a key technique for high throughput glass processing. Cutting thick glass (>500 um) using this technique possesses unique challenges, as the laser energy must be both focused to a tight spot and spread evenly in the glass depth. To learn more about several solutions for glass … Continue reading

Method For Laser Source Definition in ZEMAX™

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

ZnSe Diffractive Axicons from Holo-Or

Holo/Or now offers an expanded selection of  ZnSe Diffractive Axicons. These are 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 … Continue reading

Holo/Or Simulates Foci Elements in Optical Systems

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 Multi-Mode Laser Beams into Narrow Rings

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

C-Shape Advanced Beam Shaping for Welding Applications

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 by giving … Continue reading

Holo/Or’s Polychromatic or Multichannel Broadband Diffuser

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
