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.

Distributed feedback (DFB) laser systems offer wide tunability, narrow linewidth and high output power in a compact and very rugged setup. In a DFB diode, the frequency selective element – a Bragg grating – is integrated into the active section of the semiconductor. Thus, single-frequency operation and high coherence (coherence length 50 - 200 m) are obtained without any bulk optics, making DFB lasers particularly suitable for use within harsh industrial environments or for airborne applications.

A DFB diode can be tuned by changing either the temperature (typical tuning rate 25 GHz/K) or the operating current (1 - 2 GHz/mA). While current-tuning is favourable for rapid modulation tasks, thermal tuning has the advantage of providing extremely large mode-hop free tuning ranges (up to 1200 GHz).

To make full use of the attractive properties of DFB lasers, TOPTICA Photonics has developed the DL DFB laser system, where the laser diode is placed in our patented ColdPack housing. Four thermoelectric elements serve to stabilize laser temperature, or alternatively rapidly heat or cool the diode (temperature range 0-50 °C). State-of-the-art control electronics guarantee low-noise performance and maximum flexibility to adapt the system to the user’s requirements.
DFB lasers are available at a wide range of wavelengths, including 780 nm, 785 nm, 852 nm, 895 nm, 935 nm and 1064 nm. Applications include alkaline spectroscopy (Rb, Cs), laser cooling, gas detection (O₂, H₂O) and the generation of tunable Terahertz (THz) radiation.

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.
