摘要： Years of experimentation, testing, and refinement have resulted in designs for lasers that can produce laser beams that have a 2.94 μm wavelength and a previously unachievable output power of at least 220 W. Specific designs for such high power 2.94 μm lasers are presented herein such that those practiced in the art may achieve similar results without undue experimentation. Such a laser can include a laser rod and at least one laser pump source. The laser pump source is configured to pump energy into the laser rod to thereby cause the laser to produce a laser beam that has a wavelength of 2.94 μm. The laser beam has a maximum average power of at least 220 W. The laser beam includes a plurality of pulses that each have an energy of at least 1.5 J at 0.5 ms at 150 Hz.

摘要： Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.

摘要： A flash lamp pumped CTH:YAG resonating laser and method for operating the laser whereby the laser is capable of lasing at the 2097 nm wavelength. The method for operating at the 2097 nm wavelength include utilizing an output coupler with a lower reflectivity and minimizing the passive losses in the laser. The resulting laser is capable of operating with a lower intra-cavity energy density and increased output energy, decreasing the probability of optical breakdown of the laser components when operated.
