Abstract

We have investigated many different types of Nd solid state lasers and the passive modulator materials that can passively Q-switch, mode-lock, Q-switched mode-lock all the above solid state lasers. The mechanism of the typical Q-switched mode-lock mechanisms were proposed and analyzed in detail. In all the microchip laser developments, the only tolerance that can reduce the physics size, optimize the modulated output efficiency and minimize the component price is to use the doped single crystal semiconductor saturable absorbing modulators as we are proposing. We have used the MEMS technologies for the fabrication of the most compact, highest efficiency and most low price semiconductor substrate microchip laser. Two out of four components of the various direct generation as well as OPO generation of the microchip lasers that generate visible, near infrared and infrared wavelengths and with Q-switch, mode-lock, Q-switched mode-lock modulation could be achieved.
