Special Issue Information
Dear Colleagues,
Over the past twenty years, the sources of infrared lasers and their applications have undergone tremendous development. Starting with solid infrared lasers, using the technology of nonlinear optical frequency conversion, quantum cascade lasers and semi-conductor lasers, mid-infrared fiber lasers, and infrared lasers are becoming more compact and more powerful. At present, those infrared lasers are still flourishing. Solid lasers based on Ho- and Er-ion-doped materials are increasing in output power. Functional PPLNs are making infrared lasers more versatile, while ZGP and BGSe are extending the spectrum range of infrared lasers. Nowadays, mid-infrared fiber lasers based on ZBLAN are becoming practicable. Thanks to the development of ultra-fast laser technologies, ultra-fast infrared lasers and mid-infrared combs based on synchronized pumping techniques or mid-infrared fiber laser technology are driving infrared lasers to be more sophisticated. In recent years, the source of infrared lasers based on chip is frequently reported. This type of infrared source combines laser technology and waveguide fabrication, often utilizing chips made from Si or LNOI. Infrared chips are advantageous for modulation and compactness; these characteristics make chip-based infrared sources highly promising.
On the other hand, with the advancement of infrared laser sources, a multitude of applications for infrared lasers have been explored. Nowadays, infrared lasers are extensively employed in material processing, medical applications, remote sensing, communication and scientific research.
In conclusion, the distinctive properties of infrared laser have significantly broadened technological possibilities across various domains.

Title: High-Power 808nm and 1480nm Lasers for power-over-fiber applications at cryogenic temperatures
Authors: S. Fafard; D. Masson; C. Piemonte
Affiliation: Broadcom
Abstract: Laser diodes have been used to deliver watts of power through multimode fibers at wavelengths of 808nm and 1480nm for cryogenic applications. Ultra-sensitive silicon photomultipliers (SiPMs) allowed detecting any residual light leaked from the fibers as the temperature is decreased. Our study demonstrates that specific fiber types enable low-loss transmission compatible with cryogenic requirements and without light leakage triggering of the SiPMs. A cryogenic power-over-fiber system at 1480nm is demonstrated with 1.35W of electrical power converted over a 10m distance using multijunction laser power converters having a conversion efficiency of Eff = 67.5%.
