femtoSHAPE-SR
Femtosecond Pulse Shaper
The femtoSHAPE-SR system is an excellent choice for pulse compression and most pulse shaping applications. It is a budget-friendly solution with a good spectral resolution and small footprint. The instrument relies on diffractive shaping to offer both phase and amplitude control and comes configured to fit user’s laser source bandwidth by the proper choice of liquid-crystal-on-silicon spatial light modulator (LCOS SLM) and 4f-setup parameters. Fourier-domain pulse shaping by the programmable LCOS SLM does not require synchronization with a laser source, working equally well for laser repetition rates from 100 Hz to 1 GHz.

Phase-and-amplitude Control via Diffractive Shaping |
Pre-configurable within 400-1550 nm |
| Over 200 Independent Control Channels |
Small Footprint |
The femtoSHAPE-SR system comes complete with a compact spectrometer, nonlinear optical detection kit, and a software package enabling push-button pulse compression to the Fourier-transform-limited duration using multiphoton intrapulse interference phase scan (MIIPS) technique. The software offers built-in functionality for time-domain pulse shaping and includes all necessary calibration routines to re-configure the instrument within the SLM range as the end user’s demands evolve.
The femtoSHAPE-SR system supersedes the well-known femtoJock-D product line.

* Use diffractive shaping to enable phase-only, amplitude-only, and phase-and-amplitude control.
** Limited by the LCOS SLM type (e.g., -02: 750-850 nm; -03: 1000-1100 nm; -07: 620-1100 nm, etc.)
*** Defined as a ratio of the output power in the first-order-diffracted beam (after spatial filtering) to the input laser power. The SLM is programmed to apply “zero” phase and 100% transmission mask across the entire passband. The reported value is typical, but the actual throughput depends on the configuration.

femtoSHAPE-SR SLM Ranges |
 |
LCOS SLMs with aluminum back mirrors (-01, -07, -08) offer extended operational spectral ranges at the expense of reduced power and energy handling capabilities. Please contact our sales representative for details.
The spectral passband of femtoSHAPE-SR pulse shaper is configured to accommodate the user’s laser spectrum. It can be tuned and reconfigured within the spectral range of the LCOS SLM used in the optical setup.
