Zusammenfassung:
A prototype laser energy/power meter was designed based on the
anisotropic Seebeck effect of LaCaMnO3 thin film grown on vicinal cut
LaAlO3 substrate. The optical response of this device to the pulsed
laser and the chopped CW laser was measured from infrared to
ultraviolet. The peak voltage of the measured signal shows a good
linear relation to the laser energy and power in the measured range. It
was shown that at 1064 nm wavelength, this prototype device
demonstrates higher sensitivity than that of commercial device. (C)
