Optical characterization of overdriven CWLDs for ALEX and FWM optoacoustic microscopy. Performance occurred at 100 kHz repetition rate, 16 ns electric trigger signals, and 300 V high-voltage supply. (a–c) Optical pulse shapes of the (a) blue, (b) green, and (c) red CWLD. (d–f) Pulse energy stability of the (d) blue, (e) green, and (f) red CWLD. (g–i) Emitted wavelength of the (g) blue, (h) green, and (i) red CWLD.
