Femtosecond Pulse Shaping



The femtoJock-D is a budget-friendly solution that bridges the performance gap between the entry-level femtoJock systems and the popular MIIPS-HD line of diffractive shapers. It takes advantage of the same 2D LCOS SLM as MIIPS-HD does but uses all-reflective optics.

Product Variations:

-LCOS SLMs with metallic and dielectric back-mirrors – to be selected based on the laser source characteristics and application requirements.

Metallic back mirror Dielectric back mirror
01: 400-700nm 05: 350-420nm
07: 620-1100nm 04: 460-560nm
08: 1000-1550nm 06: 600-700nm
02: 750-850nm
03: 1000-1100nm

The pulse shaper's passband is normally optimized to fit the bottom-to-bottom spectral range of the user's laser source, subject to constrains imposed by the SLM ranges listed above.

Example: For a laser spectrum that fits within 700-800nm, an SLM with -07 coating is to be used but the shaper's passband is to be about 100nm, centered at 750nm.
