Laser measurement apparatus having a removable and replaceable beam dump

A laser measurement apparatus, comprising:

• a housing having a housing body including at least one upper housing member;
• a first compartment formed in the housing body;
• an aperture assembly mounted in the upper housing member, the aperture assembly configured to allow a beam of laser energy to propagate therethrough into the first compartment;
• a beam dump receiver formed in the housing body;
• and
• a first beam dump assembly removably positioned in the beam dump receiver, the first beam dump assembly configured to absorb a portion of the beam of laser energy.

A method, comprising:

• providing a laser measurement apparatus having an aperture assembly, a first compartment, and a beam dump receiver;
• providing a first optical module positioned in the first compartment;
• providing a first beam dump assembly positioned in the beam dump receiver;
• propagating a beam of laser energy through the aperture assembly into the first compartment;
• directing a first portion of the beam of laser energy to the first optical module;
• measuring, with the first optical module, a first characteristic of the first portion of the beam of laser energy;
• propagating a second portion of the beam of laser energy to the first beam dump assembly;
• and
• absorbing the second portion of the beam of laser energy with the first beam dump assembly.
