The manufacturer delivered 308nm fiber ultraviolet laser to NASA for atmospheric measurement

On January 9, AdValue Photonics, a leading manufacturer of fiber lasers in the United States, announced that it had delivered a high-power ultraviolet (UV) laser with 308 nm single-frequency fiber to the Goddard Space Flight Center of NASA for atmospheric measurement.

It is reported that this wavelength can achieve rapid absorption and accurate effect, and has been widely used in medical, industrial and scientific fields. According to the public statement, AdValue Photonics 308 nm single-frequency laser is the first all-solid-state version laser capable of emitting 3W average power and diffraction-limited beam. These characteristics enable the reliable and high-performance operation of atmospheric sensing systems, dermatological clinics and electronic factories around the world.

Dr. Michael Mielke, CEO of AdValue Photonics, said: "The 308 nm laser based on fiber is an inflection point in the application scenario of laser atmospheric measurement. The previous technology usually needs the use of toxic chemical lasers to produce high power effect at this wavelength. The new laser design provides this efficient optical form, and there is no inherent security, consumables and high cost of ownership challenges of the previous excimer laser."

308 nm laser is usually produced by XeCl excimer laser. In the past few decades, the progress of excimer laser technology has improved its reliability. However, due to its toxic gas (halogen) composition, the high voltage power supply required for operation and the high cost of ownership (gas consumption and component wear), this kind of laser still has unusual defects. In contrast, the fiber laser structure fully realizes the advantages of all-solid-state (gas-free), low operating voltage, and high electro-optical conversion efficiency/power conversion efficiency.

It is very important to obtain enough high single pulse energy and peak power from the all-fiber laser system. Recently, the company has successfully demonstrated 257 nm deep ultraviolet (DUV) spectrum lasers using similar technologies. In addition, AdValue Photonics is further developing a 308 nm laser with higher power, whose overall dimensions are specially used for medical and remote sensing applications. AdValue Photonics focuses on the combination of fiber laser technology, including infrared, visible light and this ultraviolet laser. Its peak performance exceeds the traditional limit.

AdValue Photonics announced that this new laser product will be exhibited at the Photonics West 2023 held in San Francisco from January 31 to February 2.
