20. A method of controlling a laser ablation system, wherein the laser ablation system includes a laser and a catheter configured to be operatively coupled the laser, comprising:
receiving, at a controller of the laser ablation system, an indication to activate the laser ablation system at a power output level chosen from a plurality of power output levels, the laser ablation system comprising a sensor positioned within the laser and configured to measure an energy of a least a portion of a laser beam generated by the laser before an output of the laser beam by the catheter, wherein each power output level of the plurality of power output levels has an associated set of configuration settings that is preconfigured and that results in the laser ablation system being activated in a start-up period at a respective power output level that is less than the chosen power output level;
sending during the start-up period, from the controller, a control signal to activate the laser ablation system using the associated set of configuration settings for the power output level, wherein using the associated set of configuration settings results in the laser ablation system being activated in the start-up period at the respective power output level that is less than the chosen power output level; and
based on activating the laser ablation system, iteratively (i) receiving an output from the first internal sensor and (ii) adjusting at least one setting of the associated set of configuration settings in the start-up period based in-part on the sensor output from the first internal sensor and a threshold sensor level in order to achieve the chosen power output level, the at least one setting being at least one of an oscillator setting of the laser ablation system or an amplifier setting of the laser ablation system, wherein the iteratively (i) receiving and (ii) adjusting in the start-up period dynamically adjust power output of the laser ablation system, and wherein the dynamically adjusting is from the respective power output level, that is less than the chosen power output level, towards the chosen power output level.
