Photonics Industries Introduces New FS-HE Line For Their Compact Femtosecond Laser Design

Photonics Industries International Inc. announces the launch of the FS-HE Air Cooled Series, a new femtosecond platform built around an all-fiber, solid-state layout that delivers clean pulses, high stability, and simple installation in a compact sealed head. The series provides up to 20 W at 100 kHz with single-pulse energies up to 20 µJ in the "HE" models, all without any external water cooling.

The FS-HE models use a rigid monolithic body with no free-space alignments and no sensitive optics exposed to the environment. System builders can mount the laser directly into equipment and run it without service adjustments, even under continuous operation.

Pulse durations are tunable from under 350 fs to 5 ps. Standard operation runs up to 2 MHz, with optional modes that reach 8 MHz. Every model includes DIGI-Burst with control of 2 to 10 sub-pulses, along with PSO and PEC for process tuning. These tools give users tight control of pulse placement and pulse energy for micromachining, semiconductors, display repair, glass cutting, surface work, THz setups, and nonlinear optics.

Beam quality is TEM00 with M2 under 1.3, pointing stability under 25 µrad, and long-term drift at or below 1 percent. Power consumption stays under 600 W, and all electronics remain inside the laser head. “With the FS Air Cooled Series and the added high-energy tier, we can support both fine-feature and high-impact work in one platform,” said Dr. Yusong Yin, CEO and President. “Users get strong pulse control, simple mounting, and reliable operation in a compact layout.”

Platform Highlights

• Up to 8 W (standard models) or 20 W (HE models)
• Under 350 fs to 5 ps tunability
• 1030, 515, and 343 nm sealed harmonic options
• DIGI-Burst and FLEX-Pulse controls
• RS232, Ethernet, GUI, and external triggering
• 22 x 10 x 4.5 in sealed body at about 47 lb

The FS Air Cooled Series is designed for industrial OEM integration, precision micromachining, semiconductor and display work, and research setups that need clean pulses and stable operation in a compact footprint.
