Alphanov will be displaying a new picosecond laser oscillator. The Pocket-size Ultrashort Laser Source (PULS) offers a monolithic solution for seeding ultrafast laser amplifiers and for applications in multiphoton imaging, laser micromachining and biophotonics.

PULS covers a large range of wavelengths. It delivers linearly polarised laser pulses with a nearly Fourier-transform limited pulse duration and a tuneable repetition rate in the 20-70MHz range.
