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
Electro-Optics Technology (EOT) supplies many components to the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) developed at Lawrence Livermore National Laboratory. Today HAPLS can produce 0.5 petawatt (PW) of power at 3.3 Hz. This is 200,000 times faster than the first petawatt laser. This laser has a repetition rate of up to 10 Hz with a … 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

Applications such as Materials Processing and Directed Energy often involve directing light from pump diodes to laser oscillators and from lasers to work pieces or targets. Delivery via fiber has proven to be an effective and flexible method to accomplish such tasks. Such applications often require excellent resistance to back reflections, very high levels of beam quality … Continue reading
Applications such as Directed Energy and Materials Processing in the >1 kW regime are now exceeding the limits of current Faraday isolator technology. Such applications often utilize coherent beam combining from fiber lasers or high aspect ratio Nd slab lasers. At >1 kW, existing Faraday isolators can exhibit both high levels of depolarization due to … Continue reading
