Broadband Operation of a Ti:Sapphire Laser Using Novel Double-Chirped Mirrors and Semiconductor Satuor (SESAM) that leads to reliable self-starting operation. With a single set of novel ultra-broadband DCMs we can tune the center wavelength of self-starting 30-fs pulses over 300 nm. The exchange of the cavity mirrors, which is usually neccessary when tuning over such a broad wavelength range, can

Improved Broadband Double-Chirped Mirrors with Controlled Dispersion Characteristicsrived from an analytical chirp law. These are then used as excellent starting designs for later computer refinement. The design procedure presented here results in improved broadband DCM designs for higher order dispersion compensation in sub-10-fs Ti:sapphire lasers.

Transient Excited-State Absorption Measurement in Chromium Doped Forsteriterk we study the kinetics of ESA with femtosecond temporal resolution using probe pulses in the ultraviolet (306 nm), visible (650 nm) and infrared (1500 nm), and estimate a nonradiative decay from the .T.(.F) to the .T. metastable level of 3 ps.

First Experimental Observation of Polarization Locked Temporal Vector Solitonsent, in a passively mode-locked fiber laser. The two intracavity orthogonal polarization modes of a 420 fs soliton pulse phase lock when the differential nonlinear phase shift arising from their unequal intensities compensates for the linear cavity birefringence. The stabilization mechanism involvin

0.28 TW laser system at 1 kHz, Scaleable to 2 TW at 1 kHz the power amplifier crystal to eliminate thermal distortions. The laser system is scalable to peak powers of > 1 TW, and we are currently constructing a 2 TW version, which uses diode pumped pump lasers, in a very compact design. This new laser system, will produce 15 fs pulses with an energy of 28

Ultra-Broadband Optical Parametric Amplifiers in the Visible and in the Near-Infrarednd 2-μJ energy are generated by a noncollinear OPA in the visible; a portion of the amplified pulse spectrum is compressed down to 7.2 fs using a thin prism sequence. IR pulses tunable from 1.1 to 2.6 μm with duration as short as 14.5 fs are achieved in a type-II OPA pumped by 780-nm, 18-fs pulses g

Tunable Visible and NIR Parametric Amplifiers at 1 kHz and Pulse Lengths Down to 10 fsm center wavelength with lengths down to 10 fs. Type II phase matching allows to access the 700 to 1100 nm range. The amplification preserves the phase of the seed light even at high efficiency. For characterization of the ultrashort visible pulses a SiC photodiode is found to be superior to thin no
