Abstract[English]
Systems and methods are disclosed for flexibly controlling laser pulses being output from a laser system. An example surgical system comprises a laser, a laser energy control system configured to regulate the amount of electromagnetic energy of each laser pulse that exits the laser system, and a laser pulse controller. The control signals communicated by the laser pulse controller may include a sub-carrier signal that modulates the amount of electromagnetic energy of the laser pulses that exit the laser system. The control signals may further include a threshold signal and/or a maximum power signal. The sub-carrier signal may oscillate between the threshold power and a maximum power.[French]
L'invention divulgue des systèmes et des procédés de commande flexible d'impulsions laser émises par un système laser. Un système chirurgical donné à titre d'exemple comprend un laser, un système de commande d'énergie laser configuré pour réguler la quantité d'énergie électromagnétique de chaque impulsion laser qui sort du système laser et un dispositif de commande d'impulsion laser. Les signaux de commande communiqués par le dispositif de commande d'impulsion laser peuvent comprendre un signal de sous-porteuse qui module la quantité d'énergie électromagnétique des impulsions laser qui sortent du système laser. Les signaux de commande peuvent en outre comprendre un signal de seuil et/ou un signal de puissance maximale. Le signal de sous-porteuse peut osciller entre la puissance de seuil et une puissance maximale.
