摘要	We report a sensitive photodetector, based on a manganite junction La2/3Ca1/3MnO3/Si, for femtosecond (fs) pulse laser energy per pulse and average power measurements. The La2/3Ca1/3MnO3/Si photodetector exhibits D* (normalized detectivity) greater than 5.229 X 10(9) cm Hz(1/2) W-1. The open-circuit photovoltage and short-circuit photocurrent responsivities reach similar to 268 V/mJ and similar to 275 A/mJ for single pulse irradiation, respectively, and the open-circuit photovoltage responsivity reaches similar to 1.7 V/W for average power illumination. The experimental results make the manganite junction a promising fs laser measurement detector and reference standard for calibrating fs lasers. (C) 2012 Elsevier Ltd. All rights reserved.
