GRENOUILLE is significantly more sensitive than SPIDER. SPIDER requires the entire beam of a Ti:Sapphire laser in order to make a measurement. GRENOUILLE requires only a few per cent of it. This allows GRENOUILLE to operate as a monitor, while using the beam for something useful. SPIDER cannot do this, as it requires the entire beam power.
