TOPTICA offers the widest wavelength coverage for diode lasers. The Research Grade Diode Lasers cater to the vast majority of spectroscopic applications in physics, chemistry and life sciences. Tunable single-mode and single-frequency lasers now cover wavelengths from 375 to 3000 nm. Spectral gaps and the deep UV regime down to 200 nm are closed by our frequency converted lasers (NLO series). Our industrial diode lasers combine first class diode technology and rock-solid opto-mechanical engineering, completed by convenient computer-control and intelligent protection measures - with record diode laser power at e.g. 405, 488 or 640 nm.
