Ultrafast Alexandrite laser with quantum-dot absorber
Main Author: Arkady Major Organization: University of Manitoba, Canada A quantum-dot SESAM mode-locked Alexandrite laser was demonstrated. Using a quantum-dot saturable absorber, pulse duration of 380 fs at 775 nm was obtained. The laser was pumped at 532 nm and generated 295 mW of average output power. |

Temporal and Spectral Measurement of Red-shifted Spectrum in Multi-frequency Raman Generation
Main Author: Zujun Xu Organization: University of Waterloo, Canada Frequency resolved optical gating is applied to study the temporal structure and spectrum of the first anti-Stokes. We observe a double peaked, and red-shifted spectrum. Together with phase information, we think there is two separated processes in the Multi-frequency Raman Generation |

Adaptive optical pulse front tilt using MEMS mirrors
Main Author: Francois Blanchard Organization: École de technologie supérieure, Canada We demonstrate an alternative pulse-front-tilt (PFT) scheme for ultrashort laser pulses using microelectromechanical system (MEMS), also known as digital micromirror device (DMD). Furthermore, using a pair of DMDs, we demonstrate a novel PFT scheme that allows fine tune adjustment of the tilt and its orientation. |

Formation of polarization dependent nano-ripple structures on diamond with femtosecond laser vortex beams
Main Author: Maryam Al-Ameer Organization: university of Ottawa, Canada We demonstrate polarization dependent laser-induced periodic surface structures (LIPSS) on diamond formed by femtosecond (fs) laser vortex pulses. We show as the laser energy and number of pulses increase, intensity distribution of the vortex beam and its field pattern are mimicked into the LIPSS. Our results confirm LIPSS are oriented parallel to the polarization of vortex laser beams with orbital angular momentum (OAM) of ±1 and ±2. |
