Introducing FEMTO-30: a high pulse energy ultrafast laser with flexible repetition rates

Fibercryst is the only manufacturer of short pulse lasers and amplifiers that utilise the innovative Single Crystal Fibre technology (SCF) – a technology that offers significant performance advantages over existing technologies.

The FEMTO-30 is Fibercryst’s latest and more powerful laser system. This 30 W laser can deliver pulse energies of 160 µJ (@ 100 kHz) in pulse widths of less than 800 fs, with repetition rates selectable between 100 kHz and 1 MHz.

A significant feature of this laser is the ability to easily and quickly change the repetition rate to favour the average power or the energy per pulse. This makes it ideal for:

  • Cutting and drilling of hard materials
  • Cold machining of polymers and composites
  • Micromachining and structuring of surfaces, for example medical devices and semiconductors

New DAli 3: Latest in automated alignment for fibre optics and waveguides

E2300SQ500The Elliot Scientific DAli 3 is the latest version of our popular automated photonic device alignment system for the following applications:

•  Fibre-to-laser diode alignment
•  Fibre-to-waveguide alignment
•  Fibre-to-fibre coupling
•  Fibre array-to-device alignment
•  Compensation for epoxy drift during pigtailing
•  Compensation for drift during long-term characterisation
•  Simultaneous alignment of input & output fibers (or arrays) to waveguide device

A typical DAli 3 system now consists of our new 3-channel E1100 piezo controller, the USB-equipped DAli 3 interface, and a PC or laptop for driving the easy to use software. Although designed to complement the piezo-driven versions of the Elliot Gold™ Series range of flexure stages, it is also suited to other piezo devices working on 0 to 150 volts.

DAli 3 incorporates the latest in electronics and uses complex software algorithms to quickly deliver precision automated alignment. It does this by locating and optimising an optical feedback signal derived from the components being aligned. It then adjusts their relative position to optimise the signal and therefore their accurate alignment.

The software and hardware package includes many features to enhance use, while also providing the necessary flexibility to allow it to be incorporated into a wide range of photonic alignment tasks for development, test and production applications.
