Laser Material Processing

Laser Material Processing Laser Material Processing uses laser energy to modify the shape or appearance of a material. This method of material modification provides a number of advantages such as the ability to quickly change designs, produce products without the need for retooling, and improve the quality of finished products. Another advantage of laser material […]

Fast generation and detection of spatial modes of light using an acousto-optic modulator

Fast generation and detection of spatial modes of light using an acousto-optic modulator AbstractSpatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information. Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask such as […]

CHARACTERIZATION OF LASER DOPPLER VIBROMETERS USING ACOUSTO-OPTIC MODULATORS

We report on a new approach to characterize the performance of a laser Doppler vibrometer (LDV). The method uses two acousto-optic modulators (AOMs) to frequency shift the light from an LDV by a known quantity to create a synthetic velocity shift that is traceable to a frequency reference. Results are presented for discrete velocity shifts […]

Acousto-optic modulation news

Acousto-optic modulation of a wavelength-scale waveguide We demonstrate a collinear acousto-optic modulator in a suspended film of lithium niobate employing a high-confinement, wavelength-scale waveguide. By strongly confining the optical and mechanical waves, this modulator improves by orders of magnitude a figure-of-merit that accounts for both acousto-optic and electro-mechanical efficiency. Our device demonstration marks a significant […]

Acousto-optic modulator has maximum average power of 1 W

A fiber-coupled acousto-optic modulator (AOM) controls the repetition rate of pulses in ultrafast lasers. A fiber-coupled acousto-optic modulator (AOM) controls the repetition rate of pulses in ultrafast lasers. It separates the pulse train with a rise time of 10 ns, has an antireflection (AR) coating, and a high damage threshold. Maximum average power is 1 […]

New Laser Product Projects for emit all 3 wavelengths Laser (808-1064-532nm)

It’s my understanding that most of the high power 532nm green lasers are actually 808nm diodes, with the 808nm beam being upconverted by Nd:YVO4 to 1064nm, then halved to 532nm by a KTP crystal. I have read that some of the high power units only measure that way because some of the IR light leaks […]

Mid-IR DFB Interband Cascade Laser 2900 – 4000nm

We divide our lasers into wavelength regions. So when we say range 2900nm to 4000nm that is a region to classify our lasers. But then the individual laser will be centered at an specific wavelength. Usually our lasers tune a few nm, the higher the wl the more nm that the laser can be tuned, […]
