A high level of fluorescence background signal rejection was achieved for solid and powder samples
by using a combination of simple low-resolution spectrograph and ultrafast gated charge coupled
device ~CCD! camera. The unique timing characteristics of the CCD camera match exceptionally
well to characteristics of a Ti:sapphire oscillator allowing fast gated light detection at a repetition
rate of up to 110 MHz, making this approach superior in terms of the duty cycle in comparison with
other time-resolved Raman techniques. The achieved temporal resolution was about 150 ps under
785 nm Ti: sapphire laser excitation. At an average excitation power up to 300 mW there was no
noticeable sample damage observed. Hence, the demonstrated approach extends the capabilities of
Raman spectroscopy regarding the investigation of samples with a short fluorescence lifetime. The
combination of a spectrometer and a gated CCD camera allows simultaneous study of spectral and
temporal characteristics of emitted light. This capability opens an exciting possibility to build a
universal instrument for solving multitask problems in applied laser spectroscopy 超快门宽增强型CCD相机 Ekspla CARS 相干反斯托克斯拉曼显微光谱仪
