Target with diffractive elements for use with laser beam generating devices

A device for use with a laser generating unit, said laser generating unit generating a reference laser beam of light, said device comprising:

• a construction laser target comprising:
• a target body formed from an optical material, said target body having an optical axis, said laser target for diffracting a reference laser beam directed from the laser generating unit to said body along said optical axis;
• and
• said body including a plurality of diffractive bodies, said diffractive bodies diffracting the reference laser beam of light directed to said target along said optical axis to produce a diffractive beam having at least one lobe at an angle in a range of about 40° to 90° from said optical axis.
