Simultaneous second- and third- order spectral phase control of Ti:sapphire laser pulses using achromatic doublet prisms.

摘要: The standard technique commonly utilized to introduce large amounts of negative group delay dispersion (GDD) into the beam path ultrashort laser pulses with low insertion losses is use a pair prisms in double pass configuration. However, one disadvantage this approach unavoidable introduction additional high-order spectral phase errors, most notably third-order (TOD) due characteristics refractive index available optical materials. In paper we provide an overview dispersive properties more than 100 common types glasses, used either as bulk stretcher or prism compressor addition, present novel method that enables independent control GDD and TOD prism-only setup. performance different combinations analyzed numerically, design guidelines are given.
