What's New?

 

PROMETHEUS Project We are proud to announce our participation in a new Horizon 2020 framework European laser surface processing project. This project is called PROMETHEUS, and pushes the boundaries of laser surface texturing technology to a new level! Within this project, we will develop a novel diffractive based M2 transformation module for high power short pulse lasers to enable the precise periodic texturing of functional surfaces with unprecedented processing speeds.

New Products

 

DeepCleave™ Laser glass cutting with ultra-short IR pulses is fast becoming a key technique for the high throughput glass processing. Cutting of thick glasses (>500um) using this technique possess unique challenges, as the laser energy needs to be both focused to a tight spot and spread evenly in the glass depth. To help our customers overcome this challenge, Holo/Or is proud to present DeepCleave, a glass cutting optical module with tight focusing (<2um spot) over a large depth of focus (>1mm in air).

 

Our module is a complete solution for cutting applications with no need for external high NA objectives! This unique elongated focus optical element was developed in order to improve the laser glass cutting efficiency and is SM1 compatible to enable easy integration into your laser machine. Why should you use Deep Cleave Glass Cutting product? Tight, diffraction limited focusing over >1mm range. Uniform intensity along the entire focal depth. Easy to integrate with existing opto-mechanics. >8mm working distance, no need for additional optics. For more information, specs and price quote click here.

 

Broadband Beam Shaping Diffuser (BD) Many laser-based systems, especially in the life science and projection 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 to give an optimal shaping solution to high power applications where more than one wavelength is required. It converts an incident single or multi-mode beam into a well-defined flat-top Round, Rectangular or Line shape. The BD is fabricated of pure Fused-Silica to endure high LDT, provides the same performance for a wide wavelength spectrum from IR to UV, has high efficiency and no zero-order

 

BD can ideally be implemented in Multi-Channel systems where there is more than one laser on the same optical path or in Tunable laser systems, and is especially suitable for high efficiency shaping of multi-mode high power lasers such as UV excimer and IR fiber coupled stacks/bars.

 

Optical Parameters Diffusion Angle Up to 20º for Round Diffuser, Up to 15º for Square/ Line diffusers Shape Flat-Top Round, Square or Line Efficiency >90% Input Single or Multi-Mode Element physical specs Dimensions 15X15mm (can be adjusted) Central Thickness 1.524mm Material UV grade Fused Silica Learn more here.

 

Technical Tips

 

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. Our Beam Foci elements are used for such applications, to shape or split the energy along the focal axis.  To support our customers in integrating our Foci elements, Holo/Or has recently developed internal tools to make full optical system design and analysis of such cases. These tools including depth of focus region simulation by geometrical rays tracing using ZEMAX™ software both in sequential and non-sequential modes. Contact us with your ZEMAX™ system design and we will be happy to simulate the performance of our Foci elements in your optical system.
