The ANTAUS microjoule ultrafast fiber laser engine features high pulse energy along with fast repetition rate, which is an ideal combination for subtle material processing applications, as well as for many kinds of scientific research. Unlike most of the competition, the ANTAUS features short pulse duration and near-perfect AC trace with almost no pulse pedestal. The system is an all-Yb-doped-fiber oscillator + amplifier with a free-space final pulse compressor. Such design architecture ensures greater stability and true turn-key operation with no maintenance as well as the highest possible output pulse energy and spatial beam quality. The output repetition rate of the system is user-adjustable in a certain range of frequencies and may be increased into tens of MHz range on custom basis. The repetition rate of any model may be modulated from single-shot via an optional output pulse slicer. The system may also include an optional feedback loop for a built-in attenuator for stabilization of the output power by an external photodetector signal. The ANTAUS systems may optionally be upgraded with the ALock PLL locking electronics for Frep syncing or Fceo locking.
The basic models of the ANTAUS family are:
The ANTAUS-10W-4u/2.5M has the smallest single pulse energy from the three, however, the average power of the system is still on par with the other two models and offers high flexibility of application, while the default output repetition rate is the highest of all three systems.
The ANTAUS-20W series has the optimal set of output parameters: significant output power, higher pulse energy and fast repetition rate.
The ANTAUS-40W series feature the highest output power and pulse energy of all the units and are suitable for power-demanding and energy-eating applications like multistage OPO and OPA pumping.
Any system can be upgraded with a novel dense-burst mode in which it can produce a burst of closely spaced pulses (~25 ns intrapulse distance) with total burst energy being much higher than the energy of a single pulse. This mode is beneficial for certain micromachining and surface structuring applications.
The laser is already being used by our customers as an OEM laser source in ophthalmology (in LASIK-type eyesight correction apparatus), as well as for THz studies, surface modification, two-photon polymerization techniques and many more. The models with up to 20 W do not require any water-cooling and feature convective cooling of the power supply unit which facilitates integration in any third-party equipment.
