  • Direct diode pumped Ti:sapphire lasers and amplifiers
    Patent number: 10367329
    Abstract: Direct diode-pumped Ti:sapphire laser amplifiers use fiber-coupled laser diodes as pump beam sources. The pump beam may be polarized or non-polarized. Light at wavelengths below 527 nm may be used in cryogenic configurations. Multiple diode outputs may be polarization or spectrally combined.

  • Single pass amplification of dissipative soliton-like seed pulses
    Patent number: 9899791
    Abstract: A system for single pass amplification of dissipative soliton-like seed pulses of 1-20 ps to produce output pulses of 50-200 fs, without requiring a stretcher. Such an amplifier relies on the inherent chirp of the seed pulse out of the oscillator instead of pulse stretching.

  • Anisotropic beam pumping of a Kerr lens modelocked laser
    Patent number: 9425581
    Abstract: Apparatus and methods for anisotropic pumping of a Kerr lens modelocked laser. Direct diode laser pumping of an ultrafast Kerr lens modelocked laser oscillator is accomplished. Diode lasers generate severely anisotropic beams, meaning the pump beam has a higher-beam-quality dimension and a lower-beam-quality dimension. By spatially overlap of the pump beam higher-beam-quality dimension and the KLM laser mode, KLM operation is accomplished. Multiple laser diode pump beams are combined in counterpropagating and same-side configurations.
