A team of researchers demonstrated that langasite (LGS) enables efficient Q-switch operation of Cr:Er:YSGG lasers at 2.79 µm. The laser is flash lamp-pumped and electro-optically (EO) Q-switched. They report 300 mJ output energy at 15 ns pulse duration at a 3Hz repetition rate, which is, as far as the team knows, the record result documented … Continue reading

The measurement of transient optical fields is critical to understanding the ultrafast physical and chemical phenomena and is key to realizing high-speed electronics and telecommunications. In a paper entitled, “Single-shot measurement of few-cycle optical waveforms on a chip”, a technique is demonstrated for single-shot waveform measurement of few-cycle mid-infrared pulses. The abstract of this paper states: “The … Continue reading
Laser lithography is a versatile technique for the creation of microstructures such as microelectromechanical systems (MEMS) and integrated circuits. It works on the same principles as photolithography but developments in laser technologies have meant that laser-based manufacturing has become increasingly popular. Photoresists Photolithography uses of a photosensitive polymer applied to a surface that is covered … Continue reading
An article published in Wiley Online, PhotonicsViews, focuses on localization microscopy, and how high–power continuous wave lasers can be used in super-resolution microscopy. Super-resolution microscopy overcomes the Abbe diffraction barrier, thus allowing resolution greater than 200-300 nm. The article details the principles of single-molecule localization microscopy (SMLM). This technique enables improved resolution by mapping individual photon … Continue reading
