New Modules in the “VisUV” ps Pulsed Laser Platform

by | Aug 22, 2016

Two new pulsed laser modules have been introduced, rounding out the “VisUV” platform line-up. Up to now, modules based on this platform provided laser pulses at 266 nm, 355 nm, and 532 nm, either individually or in combination with one or two other wavelengths. The new module “VisUV-1064” emits picosecond pulsed laser light at 1064 nm with an average optical power of more than 1 W, the “VisUV-532-HP” provides high-powered sub-nanosecond pulses at 532 nm with an average optical power of up to 750 mW.

PicoQuant VisUVWhile the previously available short pulsed (< 70 ps) green and ultraviolet versions of the “VisUV” are ideally suited for fluorescence lifetime spectroscopy and microscopy applications, the high powered green and NIR versions with broader pulse widths can be used for application requiring higher laser powers such as, e.g., LIDAR or in-situ Raman Spectroscopy.

All of these modules can be operated at internally selectable repetition rates between 31.25 kHz and 80 MHz or externally triggered at any repetition rate between 1 Hz and 80 MHz. The output beams are of excellent quality, featuring a nearly perfectly circular and Gaussian shaped profile with M2 values below 1.3.

All modules are based on a Master Oscillator Fiber Amplifier (MOFA) concept with possible frequency conversion. The master oscillator generates infrared picosecond pulses with variable repetition rates using proven gain-switching techniques. The seed laser output is then converted using either second, third, or fourth harmonic generation.
