Coherent sources of mid-infrared (mid-IR) radiation are of great interest for a wide range of scienti?c and technological applications from spectroscopy and frequency metrology to information technology, industrial process control, pho- chemistry, photobiology and photomedicine. The mid-IR spectrum, which may be de?ned as wavelengths beyond ?2µm, covers important atmospheric windows, and numerous molecular gases, toxic agents, air, water, and soil pollutants, c- ponents of human breath, and several explosive agents have strong absorption ?ngerprints in this region. The development of practical coherent solid-state sources in the mid-IR can thus provide indispensable tools for a variety of - plications in environmental monitoring and pollution control, detection of water and soil contaminants, food quality control, agriculture and life sciences, and n- invasive disease diagnosis and therapy through breath analysis. Coherent mid-IR sources also offer important technologies for atmospheric chemistry, free-space communication, imaging, rapid detection of explosives, chemical and biological agents, nuclear material and narcotics, as well as applications in air- and sea-born safety and security, amongst many. The timely advancement of coherent mid-IR sources is, therefore, vital to future progress in many application areas across a broad range of scienti?c, technological, and industrial disciplines. On the other hand, more than 40 years after the invention of laser, much of the mid-IR spectrum still remains inaccessible to conventional lasers due to fun- mental limitations, most notably a lack of suitable crystalline laser gain materials.

This book presents the papers from the 19th Workshop on Information Optics (WIO), which took place June 30 – July 4, 2025 in Barcelona, Spain. For over 30 years, the workshop has been a forum in information optics and photonics. WIO 2025 addresses advances in information optics, information photonics, imaging sciences and engineering, display technologies and 3D displays, 3D image sensing, image-based information security, image recognition, biophotonics, novel image sensors, quantum information science and technology, and more. The forum provides close interaction, collaboration, and networking among prominent scientists and educational outreach to students. The workshop consists of oral presentations by prominent scientists. The first meeting was held as Euro-American Workshop in La Rochelle in 1994. Subsequent workshops were held in Colmar (1999), Valencia (2001), Toledo (2006), Reykjavik (2007), Annecy (2008), Paris (2009), Helsinki (2010), Benicasim (2011), Quebec (2012), Tenerife (2013), Neuchatel (2014), Kyoto (2015), Barcelona (2016), Interlaken (2017), Quebec City (2018), and Stockholm (2019).
