Request InfoPicoQuant GmbHPicoQuant GmbH has unveiled 500- and 510-nm picosecond pulsed diode laser heads. Green laser emission is not generated by wavelength conversion techniques but directly by a semiconductor laser diode. The new wavelengths open the door for applications in bioanalytics, biochemistry, genetics, semiconductor characterization and quality control. The laser heads are suitable for exciting fluorescent proteins such as EYFP, mCitrine and Venus, and for widely used fluorescent dyes such as Alexa 514, Atto 520 and Oregon Green. They also fill a demand for alternatives to frequency-doubled solid-state...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueSemiconductor Laser DiodeThe Metal Can PLT5 522FA_P-M12 from ams-OSRAM AG is an off-the-shelf semiconductor laser emitter with a 514-nm wavelength output required by many life science, R&D, and diagnostics applications....BioPhotonics Jul/Aug 2023 IssueVCSEL Laser DiodeThe single-mode 850-nm vertical-cavity surface-emitting laser (VCSEL) diode from IMM Photonics GmbH is contained in a compact TO46 housing.
