A laser lithotripsy method for fragmenting a kidney or bladder stone in a patient is provided. The method includes delivering a first laser energy having a first wavelength to the stone. The stone is heated in response to the delivery of the first laser energy to the stone. The method also includes delivering a second laser energy to the stone having a second wavelength that has a higher absorption by the stone or the fluid surrounding the stone than the first wavelength. The stone is fragmented in response to the delivery of the second laser energy to the stone.
