Experiments and simulation demonstrate an instability of the intracavity pumped optical parametric oscillator against bidirectional operation. It is shown that nonlinear losses inside the signal cavity can stabilize the bidirectional operation.
Phase to frequency conversion is demonstrated with a synchronously modelocked optical parametric oscillator, with a sensitivity of 16 MHz/radian, and a phase resolution of 9ldr10-8 radian.
The carrier-envelope phase dynamics of octave-spanning Ti:sapphire lasers are analyzed based on a one-dimensional laser. It is found that self-steepening is the major contributor to the energy dependent carrier-envelope phase and that center-frequency-shifts are negligible.
Continuous channel waveguides in periodically poled KTiOPO4 with guided orthogonal polarizations are used to demonstrate type-II background-free second harmonic generation at 1505 nm with 1.2 %/(W cm2) normalized efficiency.
A novel Er:fiber/Ti:sapphire hybrid laser generates phase-locked few-cycle terahertz transients tunable from 1 to 107 THz and electric fields of up to 108 MV/cm. 8-fs pulses from the fiber laser serve as electro-optic probe.
We demonstrate a Fabry-Perot cavity, passively saturable-absorber-modelocked Yb-fiber femtosecond oscillator with up to 1.04 GHz fundamental repetition rate, enabling octave spanning continuum generation and self-referenced fCEO stabilization.
We demonstrate an ultrafast stretched-pulse fiber laser mode-locked by a carbon nanotube based saturable absorber. 123 fs pulses at 1.56 mum are generated with an output spectral width of 32 nm.
Quantum-dot mode-locked lasers are injection locked by single and two-tone master sources. Narrow linewidth, improved time-bandwidth product and wavelength control are demonstrated.
Mode-locking of the disordered cubic sesquioxide crystal Yb:LuScO3 using a reflection-type single-walled carbon nanotube saturable absorber is demonstrated under diode pumping and compared with passive mode-locking by a commercial SESAM.
