Collimator lens (21) and focusing lens (22) are provided with AR coating (23). AR coating (23) has a first reflectance for reflecting a first laser light higher than a second reflectance for reflecting a second laser light. Detector (25) detects diffusion light (DL) diffused by collimator lens (21) and focusing lens (22).

A laser processing head for a laser beam uses actuators engaged with a delivery fiber end to deflect the fiber end relative to an optical axis. The laser beam from the fiber end is collimated by a collimator and is then focused by a focusing component disposed in the head beyond the collimator to a focal point. The focal point of the laser beam is deflected from the optical axis in relation to the deflection of the fiber end. The fiber end and the actuators are housed in a sealed module. Deflection of the laser beam can be sensed by reflecting portion of the laser beam to a sensing element so a control system can monitor and control the fiber end's movement. A mode-stripper in the sealed module removes light from cladding of the delivery fiber, and an actively cooled absorber in the module around the fiber absorbs the energy.
