Atlantic HE series diode-pumped picosecond lasers offer up to 1 mJ pulse energy at 1064 nm. The series feature short (<60 ps) pulse durations, a 4 kHz repetition rate and excellent beam quality. Harmonics options include 532 nm and 355 nm output wavelengths. To ensure stable and robust operation, all optical components are integrated with a robust, monolithic aluminum block.
The stable output parameters and rugged design establish the Atlantic HE series laser as an excellent choice for micromachining applications. The high pulse energy output is capable of drilling thick samples, processing large surfaces from a single shot with specific beam profiles and generating “shark skin” effects or even nanoscale ripples. High energy pulses also provide flexibility to adopt different processes and study them in application laboratories.

Drilling holes with a defined shape in metals is crucial for various industrial applications, and fuel injection nozzles are a prime example. Green picosecond lasers (532 nm) have been proven to drill high quality fuel injector microholes that do not require post-drilling cleanup process. The Atlantic HE 532 has been used to successfully drill clean holes in 1.2 mm thick chromium‑molybdenum steel, SCM420, using 1.8 W at a 4 kHz repetition rate. The beam was focused by a 50 mm lens to fluences as high as 25 J/cm2 on the target surface while the workpiece was rotated at 1320 rpm for circular hole processing. The 20‑60 second drill time was short enough to process a through hole with a high aspect ratio and small taper.
