Abstract
1030 nm Ytterbium based solid state femtosecond lasers are key to robust NUV (3rd harmonic) and DUV (4th and 5th harmonic) generation. Industrial applications demand high average powers and often high pulse energy simultaneously. We will present the most up to date results in 3H; 4H; 5H; 6H and even X-ray generation. Lifetime, pulse to pulse and long-term stability, beam quality and especially warm-up time are critical factors for industrial applications and are often dismissed, therefore will be reviewed in detail. We will also add projections to our near future development based on the market needs. Various novel achievements already incorporated into our products such as beam shaped output directly from the module; pico- and nano- second spaced bursts in UV; peculiarities of generating UV with chirped and bandwidth limited pulses will be presented. We will discuss the lifetime testing results, the factors limiting it and the solutions aimed at extending it. We will present the results of our built-in diagnostics quality and lifetime as the requirements for accurate measurements in UV range are no less challenging.
