UV electro-optic frequency comb hybrid fiber/bulk laser system for molecular wind lidar
This work deals with a 343 nm UV laser based on the frequency tripling of a 1030 nm hybrid fiber/bulk MOPA amplifier. The seed laser source is designed to suit the molecular wind lidar application: 25 ns pulses at 40 kHz repetition rate, spectrally shaped as a frequency-comb matched to the two-waves interferometer used as lidar receiver. The signal is amplified in single-mode and LMA fibers up to a peak power of 15 kW limited by stimulated Brillouin scattering. Then, the signal is amplified in an Yb:YAG free-space amplifier to reach 36 kW peak power. Afterward, the fundamental frequency comb is converted in the UV by frequency tripling using LBO crystals with a conversion efficiency of 26%, resulting in an average power of 9.2 W (230 μJ per pulse at a repetition frequency of 40 kHz). The effect of the nonlinear conversion on the comb and its compatibility with the lidar receiver is studied.

41 W, 343 nm UV femtosecond laser based on rod-type PCF and LBO crystals
They have demonstrated a high-power ultraviolet (UV) femtosecond laser based on an all-fiber photonic crystal fiber (PCF) laser. By combining a short, large-mode-area (LMA), high-gain silica PCF with a large-core rod-type PCF, the B-integral accumulation of the system is reduced. This ultimately enabled the generation of UV laser output at a wavelength of 343 nm, with a repetition rate of 1 MHz, pulse duration of 309 fs, average power of 41 W, and harmonic conversion efficiency of 26%.
