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 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.

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Nice price diodes are either diodes, that have been superseded by better diodes or that do not run nicely in ECDL setups.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.

 Distributed feedback (DFB) lasers offer wide frequency tuning and high output power in a compact, rugged setup. The frequency selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures single-frequency operation without any bulk optics. A wide variety of DFB diodes is available from stock; custom wavelengths can be provided even in low quantities.
