<p>Methods and apparatus for material modification using laser (302) bursts including appropriately timed laser pulses (702, 704) to enhance material (314, 366) modification. In one implementation, a method for material modification comprises the steps of: providing bursts of laser pulses, wherein each burst comprises at least two laser pulses (702, 704), wherein each laser pulse has a pulse duration within a range of between approximately 10 ps and 100 ns, wherein a time between each laser pulse of each burst is within a range of between approximately 5 ns and 5 us; a time between successive bursts is greater than the time between each laser pulse comprising each burst; and directing the bursts upon a workpiece (314, 366), wherein an intensity of a primary laser pulse (702) of each burst exceeds a damage threshold (802) of the workpiece.</p> |
