Variable frequency sawtooth waveforms are often utilized as an excitation signal in a digital musical synthesizer. |
The excitation source used was an argon-ion laser-pumped, regeneratively amplified Ti-sapphire laser operating at 250 kHz repetition rate. |
The isotropic emission spectra were normalized to the corresponding absorbance at the excitation wavelength. |
This led us to shift the excitation to a lower wavelength to minimize the contribution from Rayleigh scattering in the emission spectra. |
Chemiluminescence is a special case of luminescence in which the excitation source is a chemical reaction. |
The major axes of both ellipses point nearly in the direction of maximum hair bundle excitation. |
