Due to their distinct physical nature, passively Q-switched (PQS) sub-nanosecond lasers offer a different set of controls than standard actively Q-switched systems. Understanding what are their actual capabilities - and the related limitations - is of major interest to choose the right laser for your application and successfully integrate it intoits environment.
The various operation modes and live controls offered by Teem Photonics PQS microchip lasers are described in this note: they include gate function,output energy control at constant pulse-width and
triggered or free-running modes. Other integration related inputs and outputs are also presented.
