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.
-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|
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.
