Sea tadpole

The body of the sea tadpole is semitransparent, with rose to whitish tinges and violet vertical fins. The pelvic sucker, formed from modified pelvic fins, is slightly smaller than the eye, and is often used as a diagnostic feature. More

technique, SEA TADPOLE (spatial encoded arrangement for temporal analysis by dispersing a pair of light e-fields), which can measure a very complex pulse even if it is out of focus — its complete spatio-temporal intensity and phase. More

SEA TADPOLE has applications for anything using an ultrashort pulse focus: spectroscopy, microscopy and even lithography, which sometimes uses short pulses. More

1 In SEA TADPOLE, the unknown and reference pulses cross at an angle and are spectrally resolved. We use optical fibers to introduce the beams into the device to make it insensitive to alignment (see Figure 1). SEA TADPOLE is the first practical method for measuring shaped pulses. More

SEA TADPOLE can measure even a focused pulse. FIGURE 1. A complicated pulse comprising two trains of pulses with a time-bandwidth product of roughly 400 was measured using a SEA TADPOLE device (left). More

SEA TADPOLE, we measured E(λ) of a shaped pulse that had a time-bandwidth product of approximately 100. To demonstrate that SEA TADPOLE can measure focusing pulses, we measured E(x,λ) at and around the focus produced by a plano-convex lens. More

The first technique, called SEA TADPOLE, allows for the first time the complete measurement of pulses near a focus, while the second technique, called STRIPED FISH, allows the complete measurement of mostly collimated pulses, but on a single-shot basis.DOI: 10.1117/12. More

Swamp Optics has developed SEA TADPOLE, a device designed for measuring ultrashort laser pulses in real time. Much of the development was done by Dr. Pam Bowlan during her participation in the TI:GER program. SEA TADPOLE will make its debut in 2010.www.swampoptics. More
