  • Patent number: 8724111
    Abstract: A pump-probe LFP system is adapted to a substantially lower energy requirement of a pump light source and a probe light source. The LFP system includes a photonic crystal fiber based probe light source, a pump light source adapted to produce light pulses with nanojoule or higher energy, a main laser source to generate a first beam portion to the probe light source and a second beam portion to the pump light source, a delay generator, computer, an optical modulator, and a detector. One or more lenses can be used to focus the light beams to areas less than about 1 micron on a sample, where the sample can be rastered to provide domain specific flash photolysis data of the sample.

  • Publication number: 20050180759
    Abstract: A cordless laser power meter consists of a photodetector and power meter module. The photodetector unit includes a power sensor for converting the voltage from the power sensor to a radio signal and a radio transmitter. The power sensor output provides voltage which is converted and sent to a power meter module by a radio transmitter. The power meter module includes a radio receiver and converts the voltage signal from the photodetector into the laser power display to show the measured laser power.
