  • picosecond diode pumped 1 5 μm er yb Glass Lasers operating at 10 100 ghz repetition rate
    Applied Physics B, 2010
    Co-Authors: A E H Oehler, K J Weingarten, M C Stumpf, S Pekarek, Thomas Sudmeyer, U. Keller
    Abstract:

    Stable ultrafast laser sources at multi-GHz repetition rates are important for various application areas, such as optical sampling, frequency comb metrology, or advanced high-speed return-to-zero telecom systems. We review SESAM-mode-locked Er,Yb:Glass Lasers operating in the 1.5 μm spectral region at multi-GHz repetition rates, discussing the key improvements that have enabled increasing the repetition rate up to 100 GHz. We also present further improved results with shorter pulse durations from a 100 GHz Er,Yb:Glass laser. With an improved SESAM design we achieved 1.1 ps pulses with up to 30 mW average output power. Moreover, we discuss for the first time the importance of beam quality deteriorations arising from frequency-degenerate higher order spatial modes in such Lasers.

  • nearly quantum noise limited timing jitter from miniature er yb Glass Lasers
    Optics Letters, 2005
    Co-Authors: A Schlatter, B Rudin, S C Zeller, Rudiger Paschotta, G J Spuhler, L Krainer, Nils Haverkamp, Harald R Telle, U. Keller
    Abstract:

    We report on nearly quantum-limited timing-jitter performance of two passively mode-locked Er:Yb:Glass Lasers with a repetition rate of 10?GHz. The relative timing jitter of both Lasers was measured to be 190?fs(100?Hz–1.56?MHz) root mean square. The remaining cavity-length fluctuations are below 7.5 pm in the 6?Hz–8?kHz frequency range, indicating the stability of a rugged miniature cavity setup. By actively controlling the cavity length we reduced the timing jitter to 26?fs(6?Hz–1.56?MHz). We also discuss the influence of cavity length on the practically achievable timing jitter.

  • Tunable diode-pumped femtosecond Yb-doped phosphate and silicate Glass Lasers
    Advanced Solid State Lasers, 1998
    Co-Authors: C. Hönninger, François Morier-genoud, M. Moser, L. R. Brovelli, C. Harder, U. Keller
    Abstract:

    We demonstrate tunable diode-pumped femtosecond Yb-doped phosphate (Kigre QX/Yb) and silicate (Kigre Q246/Yb) Glass Lasers. The shortest pulses were ≈60 fs for both Glasses and the tuning range for femtosecond pulses extended from 1025 nm to 1065 nm for the phosphate Glass laser and from 1030 nm to 1082 nm for the silicate Glass laser.

  • efficient and tunable diode pumped femtosecond yb Glass Lasers
    Optics Letters, 1998
    Co-Authors: C. Hönninger, M. Moser, L. R. Brovelli, U. Keller, F Moriergenoud, C. Harder
    Abstract:

    Diode-pumped Yb:phosphate and Yb:silicate Glass Lasers have been passively mode locked for the first time to the authors’ knowledge. Reliable self-starting mode locking without critical cavity alignment has been achieved with intracavity semiconductor saturable-absorber mirrors and soliton mode locking. We generated pulses as short as 58??fs with the Yb:phosphate laser and 61??fs with the Yb:silicate laser at average output powers of 65 and 53??mW, respectively. The pulse repetition rate was 112??MHz. Additionally, we demonstrated tunability of femtosecond pulses from 1025 to 1065??nm for the Yb:phosphate and from 1030 to 1082??nm for the Yb:silicate Glasses. The highest mode-locked output power was 405??mW, with 183-fs pulses from the phosphate Glass. The diode pump power was 1.68??W, corresponding to 24% optical-to-optical efficiency. The highest cw output power was 510??mW at the same incident pump power.

  • diode pumped mode locked nd Glass Lasers with an antiresonant fabry perot saturable absorber
    Optics Letters, 1995
    Co-Authors: D Kopf, U. Keller, Franz X Kartner, K J Weingarten
    Abstract:

    We demonstrate passively mode-locked diode-pumped Nd:Glass Lasers with different media such as silicate, phosphate, and fluorophosphate that are homogeneously or inhomogeneously broadened. An antiresonant Fabry–Perot saturable absorber starts and stabilizes the soliton mode-locked Nd:Glass Lasers, producing pulses as short as 130 fs at an average output power of 100 mW. With a cw Ti:sapphire pump laser we obtain pulses as short as 90 fs.
