IPG Photonics offers a line of "4f" pulse shapers that
use multiphoton intrapulse interference phase scan
MIIPS® technology for high-finesse pulse
dispersion management, with capabilities
extending far beyond the basic linear
chirp correction. Fourier-domain
pulse shaping by a programmable
liquid-crystal spatial light modulator
does not require synchronization
with a laser source, working
equally well at repetition rates
from 100 Hz to 1 GHz.

The most common application for these devices is dispersion pre-compensation to achieve a near-Fourier-transform-limited pulse duration at a target location rather than at a laser output. The shortest pulse duration results in the highest laser peak power at the target, maximizing the efficiency of non-linear processes in various applications such as multi-photon microscopy, non-linear spectroscopy, high harmonic generation, filamentation, etc.
The comprehensive pulse shaping capabilities of the femtoSHAPE line of pulse shapers are also ideally suited for ultrafast applications that benefit from specific tailoring of pulse shapes or pulse sequences in the time domain.
Microscope Detection Unit
 |
The Microscope Detection Unit (MDU) is designed to facilitate femtosecond pulse compression and measurement directly at the focal plane of a microscope, inverted or upright. It contains a nonlinear crystal for second harmonic generation (SHG) as well as other optical elements to separate SHG photons from the laser light and to couple the SHG light into a compact spectrometer via SMA-connected fiber. MDU can be chosen as an option, instead of the free-space SHG detection assembly, upon ordering a pulse shaping system, or it can be purchased separately. |

MIIPS2.x
|
|
MIIPS2.x is a major upgrade of femtoSHAPE flagship software and the core of all pulse shaping instruments. It features new MIIPS modalities, hot-swapping of multiple spectrometers, enhanced push-button calibration routines, and improved user interface. For advanced ultrafast laser users and developers, MIIPS2.x software offers streamlined acquisition of interferometric and non-interferometric frequency-resolved autocorrelations and versatile interfaces for pulse shaping applications. The latter enable straightforward synthesis of a variety of phase and amplitude masks, as well as loading user-defined profiles. MIIPS2.x software has been supplied with every pulse shaping system since 2011. MIIPS1.x software provided by Biophotonics Solutions prior to 2011 can be upgraded to MIIPS2.x.

femtoPulse Master is a standalone, easy-to-use software package that simulates the time-domain profile of a scalar optical field and a variety of nonlinear outputs based on the input spectrum and phase. The program features manipulation controls for the spectral phase and amplitude. It is available as a free "demo" version and as a full version. The full version of the software allows loading of user-defined spectrum and phase and saving all program outputs. The demo version plots all outputs but does not allow saving them. The ability to load user-defined spectrum and/or phase is also unavailable in the "demo" mode.
To purchase a license, please contact us. The full-licensed version has following functions in addition to all the others in the free demo version:
