Originally Broadcast: September 23, 2009
Overview:
Labsphere's Greg McKee will discuss the challenges that manufacturers of solid-state lighting are facing. The steps industry leaders are taking to address these issues, followed by an overview of the different test and measurement techniques and equipment that are typically used for characterizing different light sources.
Fundamentals of Photonics - Photovoltaics
Originally Broadcast: September 16, 2009
Overview:
Solar cells are an ideal source of clean, green energy because they convert solar energy directly into electricity. The challenge is improving the technology to cut costs and improve efficiency. Key performance issues include increasing the fraction of the solar spectrum absorbed and converted into electricity, improving energy-conversion efficiency, cutting costs of making and installing solar...
New Developments In Solid-State Lasers
Originally Broadcast: September 1, 2009
Overview:
Solid-state lasers have long been based on few workhorse
crystals such as Nd-YAG, but now advances in solid-state
materials have brought new types of solid-state materials
to the stage. One important class are ceramic versions of
the old crystalline standbys, which can be fabricated in much larger sizes for high-power applications. Others are new
classes of materials, such as II-VI compoun...
Challenges and Opportunities for the LED Lighting Fixture Market
Originally Broadcast: June 24, 2009
Overview:
In recent years, LED technology has made impressive performance gains, which in turn have improved the efficacy of LED lighting fixtures. The adoption of LED lighting fixtures in the general lighting market will require a new way of looking at lighting, and the value of lighting. The webcast will discuss the drivers and challenges that affect the emerging LED lighting fixture industry.
Fundamentals of Photonics: Lasers for Spectroscopy
Originally Broadcast: June 23, 2009
Overview:
Spectroscopy has always required lasers on the cutting edge
of technology. Spectroscopists seek broadly tunable lasers
for flexibility in experiments and their ability to scan across
large chunks of spectrum. They also seek lasers with single frequency output and extreme frequency stability. And for time-resolved spectroscopy, they want extremely short pulse
durations. Naturally, no single ...
