 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. |

We offer a wide array of high quality bar-based diode lasers with great thermal capacity ranging from lasers in open heatsink design to fiber-coupled diode lasers as well as vertical and horizontal diode laser stacks with wavelengths of 808 nm, 915 nm, 940 nm or
976 nm. Beginning at 30W, our high-power diode lasers are available up to several hundred watts for both constant and pulsed operation. In addition to our line of standard products, we also work in direct cooperation with our customers to find individual product solutions to their business needs. We strive for long-lived products that are every bit as dependable as they are durable - two standards of judgement that only gain on importance. Our products have a expected lifetime of 10,000 to 20,000 hours and more. This expectancy has been proven through extensive tests resulting in degradation of only 0.2 to 0.8 percent per 1,000 hours of operation. Our diode lasers are each tested individually before delivery which assures the impeccable state of each and every one of our products. All of our standard products have a warranty of 12 to 24 months. You will find a description of all of our standard products on this website. Should you have unanswered questions or wish to consult with a member of our competent sales team, please contact us by any of the means listed below.
We are here to help you find the right laser for your business needs. |

- 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.

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. |

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).

Specify your wavelength – Toptica can provide it. TOPTICA offers a large variety of wavelength-selected single-mode laser diodes from stock. Among more standard laser diodes, you will find "pearls" such as 397 nm, 715 nm or 1120 nm right from our stocklist, wavelengths for which we are probably the only supplier in the world.
TOPTICA can integrate any diode from the stock lists into a tunable diode laser system, however, you can also purchase the diode separately. Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet.
In case you can still not match your wavelength of choice, call us – and chances are very high that we can provide it within very short time. Nice price diodes are either diodes, that have been superseded by better diodes or that do not run nicely in ECDL setups. Nice price diodes will not be integrated into ECDLs by TOPTICA. In these downloads you will find wavelengths, output powers and part numbers on our regularly updated stock lists. Give us a call and we will make a reservation for the particular diode of choice for you. |
