1 Optics Lasers Detectors FREE WORKshops Date: Wednesday, January 31, 2018 Time: 8:30 am 5:00 pm Location: Moscone West (Room 2018, Level 2) The team from LASER COMPONENTS is holding a free one-day workshop that covers three topics. Come for each session or come for the entire day.

2 Part I: Optics 8:30 10:00 am How to Specify High-power Laser Optics and Polarizers Specifying the correct optical component may determine the success of an application. This session focuses on high-power laser optics and polarizers, their functional principles, essential properties, and corresponding effects depending on the application. 8:30 09:00 am High-Power Laser Optics Advantages and disadvantages of different coating technologies Tradeoffs of laser optics specifications Laser Induced Damage Threshold (LIDT) and absorption for UV wavelengths Surface flatness of laser optics after coating 9:00 10:00 am Theory of Polarization, Polarizer Types, and Utilization Explain the matter of polarization and list different types of polarizers Characterize polarizers by their specifications Describe the polarizers mode of operation in various applications Define key parameters for a polarizer in an intended application Instructors Barbara Herdt ( GmbH) André Volke (CODIXX)

3 Part II: Lasers 11:00 am 01:30 pm How to Set the Optimal Device Performance: From Pulsed Lasers in LiDAR to White Laser Light In laser scanning applications like LiDAR, many electro-optical systems using a time-of-flight concept require temporally fast optical pulses to achieve the distance resolution and detectors that can amplify very weak signals coming from the targets. The first workshop will focus on the Pulsed Laser Diodes (PLDs) part and provide an overview of challenges faced when switching high peak current fast switch hybrid laser diode circuits. The workshop on the detector part will zoom in on Silicon Avalanche Photodiodes (APDs) in terms of structure, internal gain mechanism, and noise and speed of operation. To close this session, we will provide an overview of a next generation white laser light module, which features safe high efficiency fiber delivery of light from a blue laser diode to a remote phosphor module that produces high luminance, incoherent, broad spectrum white light. 11:00 11:30 am Driving FET-based Pulsed Laser Hybrid Circuits Understanding of the various elements of field-effect transistors (FET) driver design for optimized device performance. 11:30 12:00 am Silicon APD Array Structure and Operation APD arrays requirements for special photosensitive area sizes, contours, gain variations and gaps between elements and their effects on performance. 1:00 1:30 pm Features of the World s First, High Luminance, White Laser Module Prism Awards Finalist Thanks to its high luminance output, the white laser module enables novel lighting effects, including miniature luminaires with long range highly collimated beam output, compact ultra-short throw high angle illumination, and glare-free pattern generation with sharp light gradients.

4 Part III: Detectors 1:30 5:00 pm What are the Best New IR Technologies for Your Company Choosing the right infrared detector can often be quite daunting as there are many to choose from; each with their own modes of operation, ideal performance conditions, variations, and limitations. This session will provide an overview of the different types of IR detectors available on the market today & cover their usage in industrial gas sensing applications, spectroscopy, radiation thermography and non-destructive inspection processes. This will include the following technologies: InGaAs, Extended InGaAs, and InAs Photodiodes PbS & PbSe (Lead Salt) Photoconductors Pyroelectric Detectors 1:30 02:00 pm Selecting an IR Detector for Gas Sensing Applications An understanding of the main advantages and disadvantages of common IR detector technologies covering operation, ideal conditions, available versions, and limitations of each technology How to specify a detector for your project Typical gas sensing setups for each technology How to get the best out of your detector Upcoming sensor technologies & exotic materials 2:00 02:30 High Speed InGaAs Arrays for SD-OCT and Machine Vision Prism Awards Finalist Understanding the specifications of 512, 1024 and 2048-pixel InGaAs Line-arrays with up to 400 KHz line rates, surpassing the speed requirements of medical (3D SD-OCT) and machine vision applications, consuming limited power while exhibiting stellar noise performance 2:30 03:00 pm Use of Extended InGaAs Linear Arrays Develop an understanding of the capability of 1.7 um, 2.2µm, and 2.6µm cut-off wavelength linear InGaAs arrays; and the factors that influence sensitivity continue, turn page

5 Part III: Detectors 1:30 5:00 pm 4:00 04:30 pm Recent Improvements in PbS/PbSe Detector Technology How PbS/PbSe detectors constructed The internal structure of PbS/PbSe What material mechanisms effect device performance Old vs. new, how modern manufacturing techniques effected overall detector performance 4:30 05:00 pm Differential Pyroelectric Detectors Understanding the operation of pyroelectric detectors in the true differential mode, which provides doubling of signal and an increase in D* by a factor of around 2.
