Terawatt Class Ti: sapphire Laser.

120 - fs terawatt Ti : A 1203 / Cr : LiSrAlF 6 laser system

Terawatt Cr:LiSrAIF(6) laser system.

We have developed a compact flash-lamp-pumped Cr:LiSrAlF(6) (Cr:LiSAF) laser system capable of producing peak powers in excess of 1 TW. Chirped-pulse amplification in a Cr:LiSAF regenerative amplifier produces 8-mJ pulses at a 5-Hz repetition rate. Further amplification in Cr:LiSAF yields recompressed pulse energies of 150 mJ and a pulse duration <135 fs at a 0.5-Hz repetition rate.

Optimization of a Terawatt Free Electron Laser∗

There is great interest in generating a terawatt (TW) hard X-ray free electron laser (FEL) that will enable coherent diffraction imaging of complex molecules like proteins and probe fundamental high-field physics. A feasibility study of producing such pulses was carried out employing a configuration beginning with an SASE amplifier, followed by a “self-seeding” crystal monochromator, and finish...

N ov 2 00 5 Dispersion managed mode - locking dynamics in a Ti : Sapphire laser

We present what is to our knowledge the most complete 1-D numerical analysis of the evolution and the propagation dynamics of an ultrashort laser pulse in a Ti:Sapphire laser oscillator. This study confirms the dispersion managed model of mode-locking, and emphasizes the role of the Kerr nonlinearity in generating mode-locked spectra with a smooth and well− behaved spectral phase. A very good a...

2PE-STED Microscopy with a Single Ti: Sapphire Laser for Reduced Illumination

We reported a new effective approach to carry out two-photon excitation stimulated emission depletion (2PE-STED) microscopy using a single Ti:sapphire laser system. With an acoustic-optic Bragg cell, the modulated-CW 2PE STED microscope had the benefits of both CW and pulse approaches: lower input power, simple optical scheme and no complicated synchronization. Additionally, it also took advant...
