Ytterbium (Yb)-based femtosecond lasers have gained significant attention in recent years due to their unique combination of high average power, high pulse energy, and pulse control capabilities for both industrial and scientific applications. In this talk we will review the most recent advancements in obtaining high power infrared (IR) and ultraviolet (UV), while maintaining the stability, as well repetition rate options and wavelength extensions.
1030 nm ytterbium-based solid-state femtosecond lasers are essential to robust near ultraviolet (NUV) and deep ultraviolet (DUV) generation. We will present the most up-to-date results in up to 6th harmonic generation and even x-ray generation. Lifetime, pulse-to-pulse, long-term stability, beam quality, and warm-up time will be reviewed as critical factors for successful materials processing and other applications. Last but not least, we will discuss various novel achievements already incorporated into commercial products, such as beam-shaped output directly from the module, pico-, and nanosecond spaced bursts in UV.
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.
