“…These pulse shapers give the advantage of adapting the spectral phase to the specific application. In combination with fast pulse measurement techniques and closed feedback loop, they allow the active compensation of the dispersion of an optical system . Pulse shapers based on the 4‐ f arrangement have been applied to the compression of pulses from the visible to the IR spectral range . …”

The generation of sub-optical-cycle, carrier-envelope phase-stable light pulses is one of the frontiers of ultrafast optics. The two key ingredients for sub-cycle pulse generation are bandwidths substantially exceeding one octave and accurate control of the spectral phase. These requirements are very challenging to satisfy with a single laser beam, and thus intense research activity is currently devoted to the coherent synthesis of pulses generated by separate sources. In this review we discuss the conceptual schemes and experimental tools that can be employed for the generation, amplification, control, and combination of separate light pulses. The main techniques for the spectrotemporal characterization of the synthesized fields are also described. We discuss recent implementations of coherent waveform synthesis: from the first demonstration of a single-cycle optical pulse by the addition of two pulse trains derived from a fiber laser, to the coherent combination of the outputs from optical parametric chirped-pulse amplifiers.

“…Compared to previously reported SU8 membranes [7,8], this procedure allows for somewhat stiffer membranes better adapted to the pulse shaping application. Compared to the more common mirrors fabricated from dielectric membranes [3,4,11], our method produces much more flexible mirrors, which, as shown in this work, allows for much larger distances between electrostatic actuator and mirror. As a result, we have much more flexibility in the design of a deformable mirror system.…”

“…Pulse-shaping applications require sub-wavelength position control over a range of one or a few wavelengths. A variety of works have shown successful pulse-shaping experiments with such devices based on deformable mirrors [3][4][5]. Commercially available deformable mirrors typically employ hard crystalline membranes, silicon nitride or ceramics, for example, with a small number of actuators, covered with a reflective material.…”

In this work we report on a fabrication method for producing large-area multilayer polymer membranes and describe its application to the instrumentation of a deformable mirror. This implementation allows for highly flexible mirrors in which mechanical properties vary in a controlled manner in order to better match optical requirements. In addition, the mechanical properties of such membranes allow for a large number of closely spaced actuators. We report on the mechanical properties of metal-polymer membranes and discuss their application to pulse shaping experiments.

“…In microscope objectives with high numerical aperture the pulse travels through several glass lenses, normally several centimeters, which may increase the duration of a femtosecond input pulse up to picoseconds. Several techniques [28][29][30][31][32][33][34] have been used to introduce the necessary amount of chirp to the input pulse beam in order to compensate for the average amount of GVD since a radiusdependent prechirper has not been designed yet.…”

Temporal spreading generated by diffraction in the focusing of ultrashort light pulses with perfectly conducting spherical mirrors

et al. 2013

We study femtosecond pulses at the focal plane of a perfectly conducting spherical mirror which is a dispersionless system, that is, it introduces no group velocity dispersion and no propagation time difference to the pulses after reflection. By using the scalar diffraction theory we will show that the neglected terms in the diffraction integral, when using the approximation of the bandwidth being smaller than the frequency of the carrier, have a significant influence on imaging if a laser pulse of a few femtoseconds is used in time-resolved imaging. The neglected terms introduce temporal spreading to extremely short pulses of a few optical cycles incident on the mirror, which avoids a fully compensated pulse, i.e., a one optical cycle pulse, at the focus of the mirror. The study in this paper also applies to refracting optical systems such as microscope objectives or lenses.
