A method for scribing transparent material with a laser is provided. The method includes providing relative movement between the laser and the transparent material, pulsing the laser at a first pulse repetition rate in a kHz range to establish a speed of scribing of the transparent material, and forming each of said first laser pulses with a series of second laser pulses having a second pulse repetition rate in a MHz range, wherein each of said second lasers pulses is formed from a series of third laser pulses having a third pulse repetition rate in a GHz range.
