WebMay 1, 1997 · We present a grating pair based on Carpenter prisms whose third-order dispersion is opposite that of a traditional grating pair. A properly designed stretcher{endash}compressor system with these gratings has the unique characteristic that it simultaneously compensates for second- and third-order dispersion as a function of …
Grating Stretcher for Ultrashort Pulses - LightTrans
WebApr 1, 2002 · The stretcher has a dual-grating Offner design [47] that uses 1480 lines/mm gratings at a relative distance of 486 mm and an incidence angle on the first of 56 • . ... High-energy hybrid... Webterm and leaves an opposite sign. This proves that the grating-mirror configuration is a phase conjugation of the parallel grating pair and can be used as a pulse stretcher . Fig. 3. Folded graing-telesco pe with positive dispersion However, this grating-mirror stretcher cannot be realized because, in practice, the incident hikaru opening
Investigation of spatio-temporal stretching in a duplex grating ...
WebAfter going through the grating pair, the laser pulse becomes positively chirped, that is, ... Schematic layout of a grating-based stretcher. In this case, <, which leads to a positive dispersion, i.e. the long wavelengths (in red) come first. Figure 2 shows a more complicated grating configuration that involves focusing elements, here depicted ... WebOct 10, 2024 · Among the dispersion management elements, the grating pair has the advantage of shortening the cavity length and flexible dispersion adjustment [22,23,24,25]. In this paper, we demonstrate an all PM dispersion-managed mode-locked laser oscillator with a figure-of-9 configuration, which generates 25 kW peak-power pulses at 1.03 μm. WebApr 28, 2006 · The Martinez grating pair used as a stretcher and Treacy grating pair used as a compressor. It was discovered and demonstrated that these two grating arrangements are in fact matched over all orders. The pulse can be stretched and recompressed arbitrarily keeping the initial pulse unchanged. This grating arrangement is used in most CPA … hikaru orihara
