Patent ID: 7751462

Claim:
A laser resonator block comprising: a first portion of the laser resonator block being made of a first laser resonator material, the first portion of the laser resonator block having a peaked end such that at least two sides of the peaked end are angled and coated in a highly reflective material; a second portion of the laser resonator block being made of a second laser resonator material and coated in an antireflective material, the second portion being configured with the first portion such that when a light source is pumped through the laser resonator block it produces a laser pulse by reflecting the light from one end of the laser resonator block to one of the two sides of the peaked end and then reflecting to the second of the two sides of the peaked end and then out to an output; wherein the second portion is integrated inside the first portion and the light source is pumped through one side of the first portion; a rod with a handle fastened to an end for probing the ground to locate the buried object; a polarizer; an active/passive Q-switch; a one quarter waveplate (only required if an active Q-switch is selected for use); and an output coupler; wherein the polarizer, active/passive Q-switch, one quarter waveplate, and output coupler are optically bonded to the laser resonator block in series.
