摘要： In a method, a laser pump module is set to a first power mode and pump energy is output at a first power level through the activation of a first subset of laser diodes. Laser light is emitted from a gain medium at the first power level in response to absorption of the pump energy. An operator input corresponding to a power mode setting is received. The laser pump module is switched to a second power mode and pump energy is output at a second power level through the activation of a second subset of the laser diodes. Laser light is emitted from the gain medium at the second power level in response to absorption of the pump energy.

摘要： A laser resonator includes a gain medium that produces light from pump energy and a variable light attenuator, which receives light and emits either (i) a first light including a continuous series of micropulses, or (ii) a second light including a series of macropulses at spaced time intervals, where each macropulse includes a series of micropulses. Each micropulse has a duration of 0.1 to 10 microseconds, and a duration of each macropulse is less than the time interval between each macropulse, and the micropulses have a frequency of 5 kHz to 40 kHz.

摘要： An apparatus (100) has a pump module (104) providing pump energy, a resonator (106) and a controller (187). The resonator (106) includes a gain medium (102) receiving the pump energy from the pump module and producing light; reflective surfaces (110, 156, 158, 160, 162) reflecting light produced by the gain medium back toward the gain medium; and a variable light attenuator (152) receiving light produced by the gain medium. The controller (187) controls the amount of light attenuated by the variable light attenuator such that the apparatus emits windows (306, 308, 310) of pulses of laser light at spaced time intervals, each window containing a plurality of pulses of laser light and each interval (326, 327) between windows being larger than an interval (318) between pulses within a window. The emitted windows of pulses (320, 322) of laser light heat tissue to a temperature that causes coagulation without vaporization.
