Summary
Attend one session or the entire day of the LASER COMPONENTS workshop. Get an understanding of how to select the right device or set the optimal device performance for your application. Everyone is welcome, from students, researchers, engineers and system designers to managers.

-------------------------------------------------------

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
Understanding of the tradeoffs of laser optics specifications, Laser Induced Damage Threshold (LIDT) and absorption for UV wavelengths, and surface flatness of laser optics after coating


9:00 – 10:00 am
Theory of polarization, polarizer types, and utilization
Understanding of the matter of polarization and different types of polarizers, characteristics of polarizers, the polarizers mode of operation in various applications, key parameters for a polarizer in an intended application


-------------------------------------------------------


Part II: Lasers 11:00 am – 1:30 pm
How to Set the Optimal Device Performance: From Pulsed Lasers in LiDAR to White Laser Light
The first workshop will hone in on driving FET-based Pulsed Laser Hybrid Circuits and Silicon APD array structure and operation. To close this session, we will provide an overview of a next generation white laser light 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
Understanding of APD arrayss 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
Understanding of the white laser module that 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.


------------------------------------------------------


Part III: Detectors 1:30 – 5:00 pm
IR Detectors: What Are the Best New IR Technologies for Your Company
This session will provide an overview of the different types of IR detectors available on the market today and cover their usage in industrial gas sensing applications, spectroscopy, radiation thermography and non-destructive inspection processes.


1:30 – 2:00 pm
Selecting an IR detector for Gas Sensing Applications
Understanding of the main advantages and disadvantages of common IR detector technologies covering operation, ideal conditions, available versions, and limitations of each technology.


2:00 – 2:30
High speed InGaAs Arrays for SD-OCT and Machine Vision
Understanding of 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 – 3:00 pm
Use of Extended InGaAs Linear Arrays
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.


4:00 – 4:30 pm
Recent improvements in PbS/PbSe detector technology
Understanding of how PbS/PbSe detectors are constructed, the internal structure of PbS/PbSe, what material mechanisms effect device performance, how modern manufacturing techniques effected overall detector performance.


4:30 – 5:00 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.
