The Atlantic series lasers have been designed as a versatile tool for a variety of industrial material processing applications. They are compact and OEM rugged. Featuring short pulse duration, the Atlantic series lasers offer minimized thermal damage to the material. This is becoming increasingly important in a wide range of industries: photovoltaics, electronics, biomedicine and automotive.

Dedicated for heavy-duty real industry applications, Atlantic UV models feature third harmonics – up to 355 nm output wavelength, and cover versions from 1W up to 30 W output power. Due to the redesign of harmonics module, stress on optical components is reduced, resulting in longer lifetime and lower short time thermal effects for perfect beam quality at various operation conditions. For easy and fast UV optics replacement, the Atlantic UV series model has a single wavelength output.

The innovative design employing a fiber based oscillator ensures excellent output beam parameters: M2 < 1.3 with pulse energy fluctuations < 2.5 %. All optical components are placed in a sealed monolithic block which ensures a reliable 24/7 operation.

A high repetition rate of up to 1 MHz combined with low maintenance requirements establishes this laser as a good choice for industrial, high throughput material processing systems requiring speed and precision.

The optical components are installed in a robust, precisely machined monolithic aluminum block which can be used as a separate module for customized solutions. The system is sealed to provide a long term stable operation in manufacturing environments. Designed for robust, low maintenance operation, the Atlantic offers maximum reliability due to an optimized layout, PC controlled operation, a built-in self-diagnostics system and advanced status reporting. The superior beam quality facilitates focusing of the laser beam into the smallest spot size at various working distances and enables processing of practically any material.

The Atlantic series has been designed as a low-maintenance-costs solution. All replacement of consumables can be performed at user facilities by trained technicians.

High power, speed and precision processing with picosecond laser and polygon scanner

Mimetypes-application-pdf-iconDownload PDF

In many cases, picosecond lasers have shown excellent results for material processing in diverse applications. The limiting factors remain cost and efficiency of the processes. Due to recent advancements, many high repetition lasers are suited for ablation. However, precise spatial control of a focused laser beam is required. The assessment of the Next Scan Technologies polygon scanner LSE 170 (line 170 mm; 1064/532 nm) and Ekspla Atlantic 60 picosecond laser (60 W, 13 ps, 1 MHz). The Polygon scanner is equipped with a f-theta objective with a focal length of 190 mm and provides telecentric imaging over a 170 mm long scan line. The laser pulsing was controlled by synchronizing it with polygon using SuperSync™ technology from Next Scan Technologies. The applicability of the laser-polygon pair in precise laser processing was tested, checking adjustment and correction options in precise beam spot deposition to the material.
