Photoluminescence (PL) has become a common tool to characterize various properties of single‐walled carbon nanotube (SWCNT) chirality distribution and the level of tube individualization in SWCNT samples. Sándor Kollarics et al. present in article number 1900235 the design and properties of an improved dye‐laser system, which is based on a Q‐switch pump laser. The high‐peak power of the pump provides an essentially threshold‐free lasing of the dye laser, which substantially improves the operability. The performance of the system is demonstrated by measuring the PL map (shown in the cover figure) of a HiPco‐type single‐walled carbon nanotube sample.
