Freedom Photonics' Laser Amplifier Delivers Breakthrough Performance With Perfect Beam Quality

Posted  by GoPhotonics


Freedom Photonics, a leader in photonic components, modules, and subsystems, announced that its auraTM single-mode diode laser amplifier achieved a new performance record. The result demonstrates the potential for Freedom Photonics’ aura™ diode laser chips to disrupt the market for traditional fiber lasers by delivering equivalent brightness at a fraction of the size and cost.

Dr. Jenna Campbell, Director of High Power Laser Engineering at Freedom Photonics, gave an invited paper at the 2022 International Semiconductor Laser Conference (ISLC) stating, “Freedom Photonics’ 1550 nm auraTM diode laser amplifier has achieved an output power of over 10 Watts (pulsed) with nearly diffraction-limited beam quality.” This result doubles the previous milestone announced in this year's first quarter. Compared to the current industry standard, it represents a roughly two-order-of-magnitude increase in the saturation power that can be extracted from a semiconductor optical amplifier and is comparable to the output of many fiber amplifier systems.

Dr. Paul Leisher, VP of Research at Freedom Photonics and ISLC 2022 Program Chair said: "The International Semiconductor Laser Conference is likely the most prestigious conference related to the field of semiconductor lasers and amplifiers. All submitted work undergoes a highly rigorous peer review process, and less than half of the submissions are accepted for oral presentation. Elevation of a contributed presentation to invited status, such as in the case of Dr. Campbell's talk was decided by the committee in only a handful of submissions. This is a strong indication of the perceived value and acceptance by the scientific community of the significance of the results achieved by Freedom Photonics."

The aura product line has been specifically developed to permit all-semiconductor solutions in high-power laser applications that previously relied on fiber lasers. These legacy fiber laser systems are extremely expensive, bulky, and inefficient - consuming large amounts of input power and producing excess waste heat making them difficult to cool in non-industrial environments. Dr. Milan Mashanovitch, President of Freedom Photonics noted: “Our auraTM product line is capable of achieving nearly perfect diffraction-limited output at power and brightness levels comparable to fiber laser amplifiers. We strongly believe that the introduction of an all-semiconductor solution for optical power generation and amplification will enable for the first time pushing high-power photonics products from the industrial, defense, and aerospace segments into the hands of consumers.”

Technological advancements of the aura product line are continuing rapidly; Dr. Jason Eichenholz, Co-Founder and Chief Technology Officer of Luminar, is scheduled to present a Hot Topics talk during the Plenary session of the 2023 SPIE Photonics West LASE Symposium. His talk will focus on how advancements such as this are enabling a dramatic paradigm shift in 3D sensing to unlock the potential of LIDAR technology for vehicle safety and automated driving systems.
