Thorlabs Mobile Photonics Lab One Year Anniversary @thorlabs

Uploaded September 2024 | Updated September 2026, 2 hours ago

What an amazing journey it’s been! It’s hard to believe that one year ago, the Thorlabs Mobile Photonics Lab Experience made its debut, hitting the road for the very first time!

After 13,000 miles and visits to over 40 high schools, colleges, universities, and public events, we’ve shared our love for photonics technologies with over 7,000 curious minds.

We're thankful for the response we received, and we look forward to continuing our mission of inspiring the next generation of photonics innovators for years to come!

Please visit our newly updated website at thorlabs.com/mobilelab to learn more about the mobile lab, how to request a visit, and where to meet us next.

See you on the road!

$Holiday Laser Lights | Photonics in Everyday Life Have you ever wondered how holiday laser light displays work? These laser holiday displays project hundreds of laser beams, but how can so many lasers fit into such a small package? You might be surprised to know these laser displays only need a single laser. They use something called diffraction gratings to diffract the one beam into many. Diffraction is the property of waves that allows the bending around corners. It’s a result of the waves getting bent from obstacles and edges they encounter. This can be seen when placing small obstacles like a strand of hair in the beam of a laser. The diffracted waves at the obstruction’s edges interference, creating complicated patterns of light. When small line structures are placed side by side, they form a diffraction grating and can generate multiple beams even if the structures themselves are transparent like glass or plastic. By stacking multiple diffraction gratings in a row in different orientations, a dynamic pattern of beams is created.$

$How Lights Polarization Can Change After Reflecting from a Metal Mirror | Thorlabs Insights Metallic mirrors are frequently used to steer light through optical setups. The beam’s direction and shape are typically monitored and optimized after mirror reflection, but reflection-induced changes to the beam’s polarization state are often not considered. Disregarding these changes is reasonable if the application is not polarization-dependent, but it can lead to unexpected results if the application is sensitive to polarization. Reflection from a metallic surface can change light’s polarization state because metals have complex refractive indices, which are different for P- and S-polarized light. When light is purely S- or P-polarized, incident and reflected polarization states are the same. However, linearly polarized light that is a combination of S- and P-polarized light will usually be reflected as elliptically polarized light. A further complication to consider is that the polarization state of the incident light can be changed by just tilting the mirror, since the polarization state is based on the plane of incidence. In this demonstration, we explore these concepts and show what to expect when different linear polarization states reflect from a protected silver mirror oriented at a 45° angle. The polarization state of the incident light is determined using measurements taken with a polarimeter constructed from a quarter-wave plate, linear polarizer, and power sensor. Our Stokes parameter calculations take into account the wave plate’s actual retardance, which improves accuracy. The polarization state of the reflected light is measured using a turnkey polarimeter, whose polarization ellipse display is used to visualize the dynamic polarization changes that occur as the incident linear polarization state rotates between S- and P-polarized light. 00:00 Introduction 01:13 Polarization After Reflection 03:31 Input Beam Setup Overview 04:14 DIY Polarimeter Overview 04:52 Measure QWP Retardance 7:15 Measure Stokes Parameters 8:25 Reflection of P-Polarized Input 9:34 Reflection of S-Polarized Input 11:04 Other Linearly Polarized Inputs Components used in this demonstration include: - HRS015B Stabilized HeNe Laser: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=5281&pn=HRS015B&YVI=33 - C1513 V-Clamp Post Mount, Kinematic: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=174&pn=C1513&YVI=33 - PM4 Clamping Arm: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1811&pn=PM4&YVI=33 - Posts, Ø1.5”: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1313&YVI=33 - PB2 Post Base: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1931&pn=PB2&YVI=33 - SM1B2 Isolator-to-SM1 Adapter: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=2996&pn=SM1B2&YVI=33 - IO-3D-633-VLP Optical Isolator, 633 nm: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=2996&pn=IO-3D-633-VLP&YVI=33 - RSP1C Rotation Mount: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=246&pn=RSP1C&YVI=33 - WPQSM05-633 Quarter-Wave Plate, Pseudo-Zero-Order, 633 nm: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=7234&pn=WPQSM05-633&YVI=33 - SM1A6 Threading Adapter, SM1-to-SM05: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1524&pn=SM1A6&YVI=33 - RSP1X225 Rotation Mount, Indexed or Continuous Rotation: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=246&pn=RSP1X225&YVI=33 - LPVISC100-MP2 Mounted Linear Polarizer: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=752&pn=LPVISC100-MP2&YVI=33 - PF10-03-P01 Silver Mirror: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=903&pn=PF10-03-P01&YVI=33 - NX1N Optics Mount, 16 Indexed Positions: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1546&pn=NX1N&YVI=33 - WPMQ05M-633 Quarter-Wave Plate, Multi-Order, 633 nm: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=713&pn=WPMQ05M-633&YVI=33 - S130C Power Sensor: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3328&pn=S130C&YVI=33 - PM400 Power Meter: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=10562&pn=PM400&YVI=33 - SMR1 Mount, SM1 Threads: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1433&pn=SMR1&YVI=33 - Lens Tubes, Ø1”: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3307&YVI=33 - PAX1000VIS Polarimeter: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1564&pn=PAX1000VIS&YVI=33 - KM200PM Kinematic Prism Mount: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1811&pn=KM200PM&YVI=33 - MSB46 Optical Breadboard, Mini-Series: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6327&pn=MSB46&YVI=33 - R2 and R2T Post Collars: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=2003&YVI=33 For more photonics how-to videos, visit: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=14062&YVI=33$
