Ultra FOLA

The Fibre Optic Launch Adaptor, or FOLA, is a fibre-coupling option for the Big Sky Ultra Nd:YAG laser. The FOLA has been specially developed for applications in harsh environments and it comprises an O-ring sealed, Nitrogen-purged module with factory aligned and fixed optics.

This high performance option is only available with the Big Sky Ultra, a user-friendly and rugged Nd:YAG laser, renowned for its high reliability and suitability for use in industrial environments.

The FOLA takes the output beam of the Ultra and launches it into a detachable, hard clad optical fibre to enable the laser energy to be delivered remotely. In the standard version, the module is delivered with a 3m long, 1mm diameter core (Na 0.22) optical fibre.
