High-power laser diodes deliver enhanced beam quality

The laser diodes are now available at authorised distributor Solsta.

All four of the new diodes feature Excelitas’ triple-cavity architecture, offering consistent optical output, low voltage requirements, improved conversion efficiency, and rugged TO-can packaging for high-reliability use in harsh environments.

The series spans a range of power outputs and emission areas to meet specific system needs:

• TPG3AU1S1.5 (16 W / 6 A, 40×10 μm) – Ultra-compact, energy-efficient diode ideal for short-range Time-of-Flight, 3D sensing, and portable LiDAR systems requiring tight beam collimation and low thermal load.
• TPG3AU1S03 (38 W / 13 A, 75×10 μm) – Mid-power option balancing output power and size, suited for industrial mid- to long-range ToF sensing and mobile mapping systems.
• TPG3AU1S04 (54 W / 18 A, 100×10 μm) – High-efficiency diode with a moderate aperture, optimized for extended-range LiDAR and continuous-use sensing where thermal stability is critical.
• TPG3AU1S09 (120 W / 40 A, 225×10 μm) – High-power solution for long-range industrial and automotive LiDAR, outdoor scanning, and mapping platforms requiring maximum reach and optical density.

“As demand grows for greater performance and reliability in LiDAR and sensing systems, we continue advancing our laser diode technology to meet it,” said Jens Krause, Program Manager at Excelitas. “This next-generation lineup gives customers more flexibility to optimize power, range and optical footprint for their unique application needs.

Excelitas will display the new 905 nm TPG3 Series of Pulsed Laser Diodes at Laser World of Photonics 2025 in Munich, Germany, (June 24-27), 2025, and at Sensors Converge in Santa Clara, California.
