Toptica Frequency Converted Laser Diodes

TA SHG pro 03

  • Deep UV, blue, green, yellow ...
  • All solid state laser systems
  • CW, single-frequency output

Impressive though the success story of semiconductor lasers has been, there are still several spectral "gaps", wavelengths that cannot be directly accessed with laser diodes. However, nonlinear frequency conversion techniques can be employed to generate tunable laser radiation in the UV, blue and green spectral range. TOPTICA offers state-of-the-art laser systems based on second harmonic generation (SHG), sum frequency generation (SFG) and fourth harmonic generation (FHG).

Toptica High Power, Amplified Laser Diodes

Amplified Lasers

In the past, the output of semiconductor lasers was limited and insufficient for a variety of applications. The facets of single-mode laser diodes (typically 1 x 3 ìm) suffer optical damage at high power levels, whereas with larger facets the desired spatial mode properties cannot be maintained. Powerful tunable CW light could thus only be generated with vast solid-state lasers or dye ring laser systems alongside with expensive pump sources.

TOPTICA managed to overcome these limitations with the development of the tapered amplifier TA 100. This laser system, introduced in 1998, offers not only high power, but also excellent beam quality and an extremely narrow linewidth. Researchers further benefit from convenient tunability, lowest operational costs and long lifetimes.

Toptica Tunable Diode Lasers


  • Grating-stabilized diode lasers
  • Littrow design
  • DFB diodes
  • Broadest wavelength coverage worldwide
  • Narrow linewidth

TOPTICA introduced its first tunable diode laser systems in 1995. Ever since, we have been dedicated to stay ahead in terms of power, wavelength coverage and variety. We scan the market for available laser diodes and cooperate with numerous manufacturers to supply customized new wavelengths and powers. At present our laser diodes cover the range from 373 to 3000 nm with only few gaps and more wavelengths are continuously being added. In addition, well-equipped testing facilities for diode characterization and lifetime measurements ensure accurate specifications, reliable laser operation and constant high quality.

Toptica Scientific Diode Lasers

toptica TDLS family

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.
