Focusing the laser (10 ns, 1 064 nm) through K9 glass is used to study the relation between the damage appearance of the glass and the focusing position of the high intensity ns laser pulse. When the laser pulses focus at the sample’s center, the absorbed energy increases with the pulses energy linearly and the area of damage also increases. When the laser pulses focus on the sample’s surface, the absorbed energy increases with the energy increasing at first, then decreases and tends to stabilize, which is the result of the air breakdown with large energy absorption．
