DL DFB: WIDELY TUNABLE DISTRIBUTED FEED-BACK LASER MODULE
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.
Technical Information: Specifications DL Series
The DL pro combines extended tunability with highest stability, two previously incompatible characteristics of external cavity diode lasers. This is possible only due to TOPTICA's innovative mechanical design. Based on a novel engineering approach, it provides much reduced susceptibility against environmental acoustic noise. Special care has been taken also in choosing dimensions and materials to reduce frequency shifts caused by variations of the ambient temperature. The laser can easily be set to any wavelength within the specified tuning range of 30 nm. An optimized pivot point leads to a modehop-free scan range so far unmatched by any other commercial Littrow-type grating stabilized diode lasers. As the ideal laser for many demanding applications, the DL pro ensures TOPTICA’s leadership in the market for external cavity diode lasers for the years to come.Typical applications:

TOPTICA HIGH POWER, AMPLIFIED LASER DIODES
- Tunable, high power solutions
- Semiconductor amplifier
- External cavity diode lasers
- Proprietary "RockSolid" design
- More than 1 Watt output power
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's DLX 110 RockSolid diode laser system is an outstanding tool for any application in high-resolution spectroscopy due to its exceptional narrow linewidth and extreme wavelength stability. The DLX 110 RockSolid features up to 1 W output power at selected wavelengths with single frequency and single spatial mode emission. Fine-tuning is accomplished by an internal piezoelectric drive.
The RockSolid technology reduces the acoustic and vibrational sensitivity of the DLX by a factor of approx. 100 compared to conventional external cavity diode lasers. It approaches the stability of real monolithic laser resonators.
The factory-preset wavelength can be set on request to any wavelength in the range 6 nm with respect to the center wavelength. The DLX 110 RockSolid is very attractively priced and optionally incorporates an internal output isolator (35 or 60 dB), high frequency modulation input and a probe beam output. It is also available with TOPTICAs outstanding fiber coupler (FiberDock). The laser system is complemented with a modular set of control electronics, which can be extended with sophisticated control electronics and locking modules from the establishedDL 100 series.

 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). 
If you require a complete laser system for a doubled wavelength in the range from 205 nm to 800 nm please visit the TA-SHG 110 or TA-FHG 110.  The system TA-SHG 110 comprises a tunable, grating-stabilized diode laser, a high power coherent amplifier and an external frequency doubling stage. The doubling stage is a folded ring cavity in bow-tie configuration with high mechanical and thermal stability. In combination with an active resonator length stabilization (Pound-Drever scheme), a good intensity stability is also realized. The combined system provides laser radiation particularly suitable for spectroscopic applications in atomic and chemical physics (narrow linewidth, collimated and polarized single mode beam, ideal TEM00 profile). In addition, the resonant doubling cavity SHG 110 can be easily adapted to provide maximum flexibility with any specified laser source. The SHG 110 is thus readily combined with alternative laser sources such as TOPTICA's grating stabilized diode laser DL 100DLX 110 RockSolid. One example is the FL-SHG, a system containing a high power, single frequency, tunable, cw fiber laser and the SHG module. TOPTICA offers powers greater than 400 mW at wavelengths between 520 nm and 560 nm with the FL-SHG. TOPTICA also offers competent technical support for adapting the SHG 110 to existing laser systems. In this case the SHG 110 is being offered as a 'stand alone' module in a customized solution. If you require only a frequency doubling stage please visit the SHG 110.
The TA-FHG 110 is a complete laser system consisting of an external cavity diode laser (ECDL), a high power semiconductor optical amplifier and two second harmonic generation stages (SHG 110) for producing the fourth harmonic. The FL-FHG utilizes a cw fiber laser instead of the ECDL and amplifier. Together, these systems span the UV spectrum from 205 nm up to 280 nm with powers up to 100 mW.
