The most compact, affordable, and energy efficient fs-Ti:sapphire laser in the world!

Detailed information

Product Features


With a footprint of 420 mm x 255 mm and a height of just 110 mm TENACITY is considered to be the only monolithic and most compact femtosecond Ti:sapphire laser on the market. Hence TENACITY leaves space for your application and can be comfortably integrated into existing and portable devices.


Versatile built-in diagnostics is continuously monitoring TENACITY’s operation in terms of performance and laser safety. Microprocessors and sophisticated electronics are steadily maintaining its output power against environmental changes.

Peak Power

As a diode pumped Ti:sapphire ultrafast laser, TENACITY provides one of the highest pulse peak intensities of its kind. It is therefore well-qualified for a wide range of applications whose efficiency depends on nonlinear light interactions.


Electrical energy is converted directly into pump light, which drives the femtosecond laser. Since no further frequency conversions are required, TENACITY is one of the most efficient sub-20 fs lasers in the world with less than 90 W electrical power consumption.

Time Resolution

By deploying dispersive mirrors also higher order dispersions are eliminated leading to pedestal free, clean optical pulses down to 15 fs. It helps you to capture the fastest dynamics of molecules and atoms.


VIULASE has more than 20 years of experience not only in the development but also applications of femtosecond Ti:Sapphire lasers in collaboration with renowned scientists and world-leading experts. We are excited to create perfect lighting tools for all kinds of fs-laser applications for and with people around the world.

About Us

Our Story

Vienna was the place where the shortest laser pulses of the world were generated and commercialized. We had the priviledge of taking part in this exciting journey and are determined to continue.


Technology is always on the move. Our goal is to exploit new paths to make step changes to all products in terms of stability, usability and cost.

Our Team

We have been professionally dedicated to ultrafast laser technology since 1998. Our expertise was instrumental in developing the world’s first turn-key Sub 10 fs laser available on the market.
