![A massive pulse tilt can be produced using an etalon, enabling a single-shot nanosecond FROG. The pulse is first split into two halves (indicated in red and blue) by a large-apex-angle prism. A cylindrical lens focuses both pulses to lines at the clear edges of an etalon. Inside the etalon, the pulses undergo multiple reflections and hence massive tilt (illustrated in blue for one of the pulse halves). Another lens then images the etalon onto a nonlinear medium, crossing the beams to yield a single-shot autocorrelation. This lens also focuses the pulses in the vertical direction. The nonlinear-optical signal pulse then enters an etalon spectrometer and camera (not shown). The inset at upper left shows measured and retrieved traces of a microdisk laser pulse; the inset at lower right shows measurements of the retrieved microdisk laser pulse [8].](https://img.laserfocusworld.com/files/base/ebm/lfw/image/2016/01/1401lfw01frontis.png?auto=format,compress&fit=crop&q=45&h=139&height=139&w=250&width=250)
