Compact Diffractive Laser Device

I am developing a small, filtered laser module and need an experienced photonics Engineer to assist. The priority is the diffractive optics: shaping the beam with an axicon-based element and coupling it cleanly through the rest of the laser system. Once I provide the specification, your job is to translate those requirements into a practical, test-ready design. Core focus • Diffractive optics: model, design and optimise the axicon element that sits at the heart of the device, then validate its performance through simulation and tolerancing. • Laser module integration: ensure the designed element mates mechanically and optically with the diode, filter stack and any relay optics already sketched out in my draft. - The whole design must be compact Additional expectations • Source off-the-shelf or rapid-turn custom parts locally so you can bench-test prototypes. • Highlight any cost-saving substitutions without compromising performance. • Supply clear design files if required (such as a suitable housing) I value direct, engineer-to-engineer communication—please respond with a brief outline of similar diffractive projects you’ve handled.
