Abstract:
A laser system, the system comprising:a. one or more laser emitters forming a laser stack, wherein the laser emitters emit a laser pulse during an on-time and stop emitting the laser pulse during an off-time; b. a heater resistor coupled to the laser stack and for stabilizing a temperature of the laser stack; c. a heat reservoir coupled to the laser stack and for storing a heat flow from the laser stack during the on-time and release the heat flow to the laser stack during the off-time to maintain a specified temperature range of the laser stack; d. a case spacer coupled to the heat reservoir and for conducting the heat flow from the heat reservoir to maintain the specified temperature range of the laser stack, a thermal resistance of the case spacer being higher than a thermal resistance of the heat reservoir; and e. a temperature monitor coupled to the laser stack and for monitoring the temperature of the laser stack.
