Embodiment Construction
[0026] The invention adopts active electro-optic Q-switching-saturated absorber double-walled carbon nanotubes (DWCNT-SAs) passive mode-locking dual-loss modulation technology and frequency multiplication conversion of nonlinear crystals, and utilizes electro-optic modulation with fast switching speed and Q-switching pulse width Narrow, stable performance, low price of DWCNT-SAs saturable absorber, easy growth control, wide saturable absorption band advantages, the electro-optic modulator and DWCNT-SAs saturable absorber are placed in the resonant cavity at the same time, through the The oscillating fundamental frequency infrared laser (1.06μm wavelength) infrared laser operates as a Q-switched mode-locked laser with active and passive dual-loss modulation, and optimizes the design of the laser's professional resonant cavity parameters to make the repetition rate of the Q-switched mode-locked fundamental frequency laser Depending on the repetition rate of active electro-optic m...
