Abstract

Nanocrystalline NiFe₂O₄ (Nickel Ferrite) particles were synthesized using the coprecipitation technique and subsequently their nonlinear optical properties were studied using the open aperture Z-Scan experiment employing nanosecond and femtosecond laser pulses. A significant optical limiting is observed in both cases showing that NiFe₂O₄ is a potential optical limiter having a broad temporal response, useful for device applications.
