aeroPULSE FS high power femtosecond lasers

aeroPULSE FS is a portfolio of industrial-grade femtosecond fiber lasers based on NKT Photonics world renowned Crystal Fiber platform.

aeroPULSE FS femtosecond laser control unit This family of rugged and compact OEM femtosecond lasers use state-of-the-art mode-locking technology to deliver ultra-short femtosecond pulses with outstanding long-term stability, superior pulse-to-pulse stability, low noise, and excellent TEMoo mode quality.

As standard, the aeroPULSE FS is available with output powers up to 20 W emitting at 1030 nm. Other wavelengths, including green, are available upon request.

The aeroPULSE FS lasers were developed for demanding 24/7 OEM applications, highlighting unit-to-unit consistency and uptime, low cost of ownership, and ease of integration. Designed for the stringent requirements of materials processing and micromachining applications where its superior reliability are mandatory product attributes. Every feature of the aeroPULSE is designed for continuous and consistent operation in demanding applications.

The system configuration consists of a 19” rack-mountable control unit and a very low profile laser head that can be mounted either horizontally or vertically. The complete system is water-cooled supporting high output power performance.

The system can be remotely controlled via an RS-232 interface, and incorporates extensive on-board data logging of key parameters. Our proprietary manufacturing technology ensures product quality while our tightly controlled supply chain makes for consistency.
