1. Safety Beware of the risks involved when working with your laser. Check your laser eye safety class and follow the recommendations. Follow the guidelines provided by the manufacturer of your laser source. 2. Recommended equipment for installation • Gloves •... -
Page 5: Typical Optical Setup
4. Typical optical setup A typical optical setup for the generation of Bessel beams alignment mirrors and a reflective axicon� A telescope (optional) and/or ring-shaped beams includes a collimated laser source, might be needed to accommodate the laser beam diameter� The optical elements needed are: •... -

5. Installation Preliminary • Make sure that you have all the necessary tools� straight edge ruler • Start by placing every optical element with their holders • Place the beam block where needed (It will be placed after on the optical bench, following the schematic described in the optics currently being aligned to avoid any incident) section 4�... -
Page 7: Telescope Installation (Optional)
Telescope installation (optional) The laser beam diameter may need to be adjusted to fit the axicon with the recommended dimensions. To adapt the collimated beam diameter, a telescope must be installed. Equipment needed: • 1x Lens L with an EFL ƒ , with mounts •... -
Page 8: Pre-Alignment Mirrors
Pre-alignment mirrors The alignment mirrors allow you to adjust the laser beam optical axis with the requested input optical axis of the axicon. Equipment needed: • 2x Alignment mirrors, with kinematic mounts • 1x Reflective axicon, with 2” rotation mount Procedure: Place the beam block in front of the axicon mount (currently Align the first mirror so that the beam exiting the second mirror... - Page 9 Once broad alignment is completed, turn the source off and move the beam block from being in front of the axicon mount to behind the axicon� Right now, there is still a mirror in the axicon mount� Adjust Using the IR card, scan the beam path to verify that the beam the mount angle to have the reflected beam propagating at the follows the rail�...

Page 10: Axicon Alignment
Axicon alignment When the mirror in the axicon mount is correctly positioned, edge that can be used to achieve the correct rotational position� replace it with the axicon� The axicon’s substrate has a flat This flat edge should be placed at the top� Axicon’s flat edge With the IR card, scan the beam path to see where the Bessel beam and the ring-shaped beam are generated:... - Page 11 Once this general alignment is obtained, place the camera on • Once the mirrors have been fine-tuned, a proper the rail, and set it up (sensitivity, contrast…) to observe the measurement of the depth of field of the generated beam generated by the axicon� If necessary, place a ND filter in Bessel beam can be performed�...
