Toptica BoosTA pro High-Power Tapered Laser Amplifier

The TopticaBoosTA pro, TOPTICA’s new stand-alone optical amplifier, increases the output power of a DL pro or any other linearly polarized master laser by up to 20 dB (x100). Following TOPTICA’s well-established pro-technology, the TA chip is mounted in a compact unit with optimized heat management and beam-shaping optics. A compact, external power supply (DC HP) drives the amplifier head and allows effortless operation - even of current-hungry TA chips at wavelengths with lower gain. Researchers thus benefit from output power levels up to 3.5 W.

The BoosTA pro head includes a high-bandwidth current modulation board, which – when used in a closed feedback loop – allows compensating power fluctuations of the master laser by adjusting the amplifier gain. The board also features a protective circuit to avoid the risk of electronic chip damage. The beam management of the seed laser can be greatly simplified by optional fiber input coupling. Other options are optical isolators and fiber output coupling. The BoosTA pro head has sufficient space for a 60 dB isolator to protect the TA chip from back reflections.

Toptica TA pro Tapered Amplifier Laser System

The TA pro is the flagship product of TOPTICAs high power tunable diode laser solutions.  Its tapered amplifier technology allows for high power with excellent beam quality, while at the same time maintaining the favorable spectral properties of the pro master laser. The TA pro is a completely revised version of a very well-established laser system, the TA 100. It has been optimized for extreme stability and ease of use, and has proved these properties in numerous tests in TOPTICAs and customers´ laboratories.

The DLC TA pro is equipped with TOPTICA's all digital DLC pro control electronics: with lowest noise and drift and more convencience, it also offers highest amplifier currents up to 10 A and additional protection for the amplifier chip. Also available with the economic SYS DC 110 laser electronics.

Toptica DFB pro Distributed-feedback laser

Toptica Distributed feedback (DFB) lasers unite wide tunability and high output power. The frequency-selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures continuous single-frequency operation. Due to the absence of alignment-sensitive components, DFB lasers exhibit an exceptional stability and reliability. The lasers work under the most adverse environmental conditions – even in the Arctic or in airborne experiments.

Three laser heads, designed specifically for DFB lasers, accommodate different diode packages: the compact DFB pro and its “big brother” DFB pro L integrate 9 mm or TO3-type diodes. The DFB pro BFY offers a dedicated laser head for butterfly-type diodes.

Owing to their wide continuous tuning range, DFB lasers lend themselves particularly to applications in atomic and molecular physics, gas sensing, phase-shifting interferometry, and continuous-wave terahertz generation.

The PowerLock option automatically compensates residual drifts caused by changing environmental conditions, offering unvarying stable laser output with constant power. Fiber-coupled systems using the FiberMon option can monitor the optical power coupled to the SHG output fiber. In combination with the FiberMon option, AutoAlign and PowerLock are also available for fiber-coupled systems.
