HELIOS

Coherent HELIOS lasers, in the IR and the Green, allow for picosecond precision in a variety of micromachining and microelectronics applications.

The high peak power from pulse durations as low as a few hundred picoseconds allows HELIOS to deliver an effective number of photons to the sample. The laser pulse is also delivered with high precision in timing due to its electro-optical Q-switch. This Q-switch is faster and more precise in switching than standard acousto-optical devices found in competitive technology. The digital controller design is easy and cost-efficient to integrate into OEM designs. Combine this with the rugged design and components from Coherent’s vertical supply chain, and this makes HELIOS the low cost of ownership solution in micromachining and microelectronics applications.

Actively Q-Switched DPSS Laser

The actively Q-switched Helios laser allows for better precision in a variety of micromachining and microelectronics applications.

Helios translates MOPA (Master Oscillator and Power Amplifier) technology into performance enabling applications. Delivering pulse lengths of hundreds of picoseconds in a compact and rugged package, the Helios allows for results not possible with longer nanosecond pulse lengths.
