A laser system is proposed that is configured to provide a pseudo-CW signal at room temperature. The system utilizes an array of pulsed lasers that are controlled (in terms of turning "on" and "off") to provide, in combination, a quasi-CW output signal. The activation of each individual laser is controlled to turn "on" and "off" in a predefined sequence, where at least one laser is "on" at any given point in time. Thus, by combining the outputs from the plurality of pulsed lasers onto a single output signal path, the resultant output signal from the system will be a pseudo-CW signal (the amount of "ripple" present in the signal controlled by factors such as the number of individual lasers in the plurality of lasers, the duty cycle of each individual laser, etc.). The duty cycle of the individual lasers can be controlled to provide a high power output signal (higher duty cycle), or provide a high wall- plug efficiency of the system (lower duty cycle). |
