PRODUCT UPDATE LASERS Picosecond microchip laser


Thorlabs has released a passively Q-switched laser producing 500ps pulses centred at 1,030nm. The microjoule-level pulse energies produced at kilohertz repetition rates enables multiple applications including material processing, harmonic generation, lidar, photoacoustic imaging, and laser- induced breakdown spectroscopy. A fibre- coupled pump source in the head produces exceptional beam quality for efficient micromachining applications. With a compact footprint measuring 76.2 x 136.3mm and taps for 30mm cage system compatibility, this laser can be conveniently integrated into an existing system and paired with any number of Thorlabs’ cage-mounted components, including optics, motorised shutters and galvo scanners. This turn-key solution includes custom


temperature control and laser drive electronics in a separate control unit for optimised stability and performance. An SMA trigger output is provided on the laser head. www.thorlabs.com


Jasper 100


Femtosecond fibre laser manufacturer Fluence has released the Jasper 100 laser. The laser delivers an extremely useful set of parameters including a maximum average power of 100W at 200fs pulse duration, while maintaining excellent temporal pulse shape with a Strehl ratio of 96 per cent. It operates at repetition rate of 20MHz, delivering 5mJ of energy per pulse. The laser can create repeatable, precise and clean micro features in applications such as patterning, marking, micro- and nanostructure formation for producing superhydrophobic or anti-icing surfaces on various materials, as well as laser milling, glass cutting and display processing. While some competing lasers claim output power of up to 300W, these free-


DX series UV and green lasers


Photonics Industries’ DX series 355nm UV DPSS lasers deliver pulse energies of >1mJ/pulse and output powers between 15-50W, over a wide repetition rate of <20kHz to >500kHz, with beam pointing stability at <25μrad. All of this is offered at around 10 per cent wall plug efficiency. The firm’s DX series green laser (532nm)


offers a pulse width of <30ns at 400kHz repetition rate. The laser also offers output powers at 30, 50, 65 and 100W, over a wide repetition rate up to 900kHz. This DPSS laser offers a wall plug efficiency of around 17 per cent.


The lasers come in a small lightweight package, offering a monolithic all-in-one design with no need for a separate utility module. Complete pulse control is provided by the


software’s GUI interface, for adjustments of pulse energy control and burst mode. To address changing ambient temperature conditions, the DX series lasers have a wide operating temperature range. With fast warm-up times and stability, these


systems offer exceptional laser performance in micromachining applications such as cutting, scribing, marking, and drilling. www.photonix.com


WWW.LASERSYSTEMSEUROPE.COM | @LASERSYSTEMSMAG SUMMER 2021 LASER SYSTEMS EUROPE 19 Dart 8 picosecond laser


space lasers are costly, include mirrors that suffer from misalignment issues, have longer pulse durations and require more maintenance at lower duty cycles than the Jasper 100. Jasper femtosecond lasers are built using an all-fibre, monolithic and SESAM-free oscillator. They pose no risk for misalignment, providing a dependable, high- performance laser for disparate industrial applications. https://fluence.technology


Novanta has introduced the Dart 8 picosecond laser. Designed for micromachining, the laser delivers exceptional beam quality, including beam roundness of more than 93 per cent across two Rayleigh lengths, ensuring clean and precise material processing. Engineered by Novanta brands


Laser Quantum and Arges, the Dart 8 is configured for OEMs in the micromachining field. Its compact size enables it to be easily integrated into new and existing platforms, mounted either vertically or horizontally, providing flexibility and ease of integration. The Dart 8 is ideal for processing an


array of materials and is designed to deliver a high degree of reliability when cutting complex and precise structures. The picosecond laser is compatible with the Novanta portfolio of scan heads to maximise optical parameters and throughput, while maintaining precision. www.novanta.com
