Paper Abstract

Based on laser crystals, the testing principle of fluorescence lifetime on μs is introduced and a practical device on this principle is designed. The testing system includes exciting source, light path system, detecting circuit, signal disposing circuit and LCD display circuit. Achieved by pulse sampling technique, this device with small size can display the fluorescence lifetime value on LCD directly and reliably, and it measures the fluorescence lifetime of Nd:YAG crystal and doped Nd glass in lab as 240μs or 330μs separately which conforms to the theoretical value very well.
