A method and system for treatment of incontinence, urgency, frequency, and/or pelvic pain includes implantation of electrodes on a lead or the discharge portion of a catheter adjacent the perineal nerve(s) or tissue(s) to be stimulated. Stimulation pulses, either electrical or drug infusion pulses, are supplied by a stimulator implanted remotely, and through the lead or catheter, which is tunneled subcutaneously between the stimulator and stimulation site. For instance, the system and method reduce or eliminate the incidence of unintentional episodes of bladder emptying by stimulating nerve pathways that diminish involuntary bladder contractions, improve closure of the bladder outlet, and/or improve the long-term health of the urinary system by increasing bladder capacity and period between emptying. Moreover, the system and method allow a patient to be taught to receive one or more patterns of neural stimulation that can be prescribed by a physician and administered without continuous oversight by a clinical practitioner.

A laser system is enabled to generate laser beam stably for a long term by avoiding the decay of nonlinear optical crystals due to moisture. The fundamental laser wave at a wavelength of 1064 nm is emitted from the pumping chamber unit of the solid-state laser device. The fundamental laser wave enters the first nonlinear optical crystal unit (20). The wavelength of the laser beam is converted into a half by the first nonlinear optical crystal unit (20). The converted laser beam emanates out of the unit. The fundamental laser wave and the second harmonic laser wave are introduced into the second nonlinear optical crystal unit. Each of the laser beams is converted into the third harmonic laser wave (three-time fundamental frequency) or the fourth harmonic laser beam (four-time fundamental frequency) and the laser beam comes out of the exit-window (34). The nonlinear optical crystal units (20), (30) are held in a hermetically sealed cell whose inner surface is treated to be water-repellent. As the dry atmosphere is kept by means of isolating the nonlinear optical crystal from the outer air, the crystals can avoid decay due to moisture and the damage on the crystals can be reduced.
