“…The narrowing of the emission line is accompanied by strong enhancement of the emission intensity. These observations are similar to those reported by Lawandy et al [96,108] and are explained as the ASE, which represents a feedbackless mechanism, in spite of being qualified as the lasing with nonresonant feedback in the current literature. The emission band collapses (see Fig.…”

Abstract. Currently optically pumped mirrorless lasing is represented by three distinct branches, which concern lasing in different types of the gain media: optically random and photonic media, and microcavities. This article is a first part of our review on optically pumped mirrorless lasing, with the random lasing in scattering media being a main subject. The other mirrorless lasing mechanisms will be addressed in the second part. Considering light localization as a key function of the feedback, we discuss possible mechanisms for the light localization in the scattering media. Special attention is paid to the Anderson light localization. The other mechanisms of the light localization in the scattering media concern high Q-resonances in local microresonators, which exist due to structural inhomogeneities in the scattered media. Applications of the random lasers are shortly reviewed.

“…Random lasers have been first theoretically proposed in 1967 [4] and experimentally demonstrated in 1986 [5]. Since then, this has been a topic of intense theoretical and experimental research [6][7][8][9][10], revealing a broad spectrum of random lasers with coherent and incoherent feedback based on solid [1,[5][6][7] and liquid [8] gain media as well as biological soft matter [9,10].…”

Pulse-to-pulse instability in the emission from a random laser based on Nd:Sc 3 (BO 3 ) 4 ceramic with immobile scatterers was studied below, at, and above the stimulated emission threshold P th . The correlation between pumping and emission intensities was found to be surprisingly low, especially in the vicinity of the lasing threshold. When the sample was excited by reasonably stable (±5%) pumping pulses, a strong fluctuation of output intensities was observed in the range of pumping energies P th /2 < P < 2P th -the range in which the Lévy statistics of emission fluctuations has been predicted in random lasers. We thus report on experimental evidence of the Lévy statistics in a random laser with firmly fixed scatterers.

“…Also, IPRLs are opening a host of possibilities for lasers in the next‐generation wearable and soft optoelectronics. It is highly anticipated that IPRLs can be further applied to photonic integrated circuits for communicating and computing, opto‐microfluidics for biodiagnostics and biostatistics, or smart prints for identification and authentication …”

Printing technology has led to a multitude of revolutions in design, conception, fabrication, and application of optoelectronics nowadays especially for wearables and one‐off devices. Recent advances range from solar cells, batteries, sensors, LEDs, displays, biomedical widgets to smart tags. Inkjet‐printed random lasers (IPRLs), demonstrated here, fill in the crucial but missing piece of the puzzle in printed optoelectronics as well as progress in laser research. A broad emission spectrum of IPRL inks covering more than 75% gamut of CIE color space is successfully exploited and well adopted by commercial desktop inkjet printers. Furthermore, based on the digital, ink‐efficient, mask‐free patterning, and drop‐on‐demand printing technique, a series of long‐anticipated proofs‐of‐concept including on‐chip laser lighting modules, red‐yellow‐green‐blue pixel‐based laser displays, and ink‐crypto/laser‐coded security printing technique are also demonstrated.
