Laser micromachining is rapidly becoming the material processing technology of choice for numerous small scale, real world applications. New advances in diode pumped solid-state (DPSS) lasers are enabling material processes once found  only in research laboratories to be incorporated into growing numbers of production lines

From its inception, the Atlantic – a new generation picosecond high power and high pulse energy laser – has been designed as a versatile tool for a variety of industrial material processing applications.

The Atlantic is an OEM rugged, compact laser with 60 W output power at 1064 nm. Featuring short pulse duration (typically 13 ps) Atlantic series laser offers mimimized thermal damage to the material, what is becoming more and more important in wide range of industries: photovoltaics, electronics, biomedicine, auto.

Innovative design, employing fiber based oscillator ensured excellent output beam parameters: <1.3 with pulse energy fluctuations < 1.5 %.  All optical components are placed into sealed monolithic block thus ensuring reliable 24/7 operation.

High, up to 1 MHz repetition rate, combined with low maintenance requirements establishes this laser as good choice for industrial, high throughoutput material processing systems, requiring speed and precision. Optical components are installed in a robust, precisely machined monolithic aluminum block, which could be used as a separate module for customized solutions. The system is sealed to provide long term stable operation in manufacturing environments. Designed for hands‑free operation, the Atlantic offers maximum reliability due to an optimized layout, PC‑controlled operation, a built-in self-diagnostics system and advanced status reporting. Superior beam quality allows easy focusing of the laser beam into the smallest spot size at various working distances and enables processing of practically any material. The Atlantic has been designed as a low-maintenance-costs solution. All replacement of consumables can be performed at user facilities by trained technicians.

Advantages of picosecond lasers

Impressive progress has been made in picosecond laser technology, making these lasers a reliable tool for a host of industrial micromachining applications that were impossible a few years ago. The picosecond pulse duration is comparable with the time of electron‑phonon relaxation and is short enough for “cold” ablation.
The Atlantic also offers a UV wavelength option that lowers the ablation threshold of many materials. This means a lower pulse energy, which further reduces the thermal stress of the workpiece. Picosend lasers also have a number of advantages over the shorter‑pulsed femtosecond lasers. With no need to stretch and compress pulses for amplification, picosecond lasers have a less complicated design and are therefore more cost-effective and reliable. At the same time, picosecond pulses remain sufficiently short for very precise and stress-free micromachining. Picosecond lasers are capable of processing a wide range of micron scale features in almost all materials, including:

  • Metals
  • Semiconductors
  • Diamond
  • Sapphire
  • Ceramics
  • Polymers
  • Composites and resins
  • Photoresists
  • Thin films
  • ITO films
  • Glass
