About QS Lasers

QS LASERS develops compact, air-cooled diode-pumped laser modules engineered for OEM integration into high-performance scientific, industrial, and medical systems. Specializing in Q-switched and gain-switched solid-state lasers, we deliver sub-nanosecond pulse widths down to 90 ps with high peak power and excellent beam quality. Our systems are based on Nd:YAG and Nd:YVO₄ crystals, offering output at 1064 nm and 1342 nm, as well as 671 nm via second harmonic generation. These wavelengths support a range of applications including LIBS, time-gated Raman spectroscopy, biomedical imaging, and multispectral LiDAR. Designed with OEM needs in mind, our lasers are compact, air-cooled, and optimized for easy integration into equipment where size, reliability, and precision are critical. We support both single longitudinal mode (SLM) and narrow linewidth configurations for applications requiring spectral purity and pulse consistency. Our proprietary gain-switched amplifier technology enables pulse shortening well below traditional Q-switch limits, achieving fast, clean pulses while maintaining system simplicity. With a modular approach and flexible engineering, we work closely with OEM partners to adapt our platforms to their exact performance and interface requirements. With deep experience in diode-pumped solid-state laser development, our team delivers robust, integration-ready modules backed by responsive support and a commitment to long-term partnership.
