We report on orthogonally polarized dual-wavelength operation of a continuous-wave Yb:KGW laser. Gain equalization of the two wavelengths with the Nm- and Np-polarizations was attributed to the effect of anisotropic thermal lensing.
We demonstrate substrate-transferred crystalline coatings, based on epitaxial Bragg mirrors directly-bonded to fused silica, exhibiting an unprecedented tenfold reduction in Brownian noise. These mirrors promise a significant advancement in the performance of precision optical interferometers.
We propose and experimentally demonstrate new beam solutions in form of azimuthally symmetric higher-order Bessel-Gauss beams. We experimentally observe these beams as higher-order eigenmodes in optical resonators consisting of aspheric mirrors.
We explore experimentally a new regime of operation for mode locking in a Ti:Sapphire laser with enhanced Kerr nonlinearity, where the threshold for pulsed operation is lowered below the threshold for continuous-wave operation.
We have generated 16.5-MHz, 400-fs pulses with a power of 490 W in a thin-disk ring oscillator under development for intra-cavity high-order harmonic generation.
We describe an intracavity doubled continuous wave singly resonant OPO (CW-SHG-SRO), exhibiting tunable operation between 585 and 678 nm. Its frequency is locked to better than 1 kHz over 1 s relatively to a cavity.
We demonstrate a degenerate mid-infrared frequency comb OPO with a fractional cavity length pumped by an ultrafast 100-MHz Er-nber laser. This produces a 600-nm wide output near 3μπι with a repetition rate of 500 MHz.
Power scaling of Kerr-lens mode-locked Cr:ZnS femtosecond oscillator allows reaching 1 W output power and pulse energies over 8 nJ. Soliton and chirped-pulse regimes result in 68 fs and 0.8–2 ps pulses, respectively.
In an interferometric measurement, the quantum radiation pressure noise, which is due to quantum intracavity intensity fluctuations, gives rise to mirror displacement fluctuations and sets a limit in the displacement sensitivity. We have designed a table-top experiment to demonstrate this effect and realize various quantum optics experiments with an optomechanical system.
