Tunable Dye Laser

A quasi-continuous, widely and rapidly tunable optical parametric oscillator (OPO) with high average power is described. A Cu-vapour laser pumped, tunable dye laser has been used to pump a LiNbO3 OPO at a repetition rate of 6 kHz. Rapidly tunable infrared radiation in the range of 0.83–2.42 μm has been obtained with average powers as high as 136 mW in the short-wavelength branch of the output.

High Average Power

We report on an eye-safe, transform-limited, millijoule energy, and high average power fiber laser. The high gain and short length of the NP phosphate-glass fibers enable the SBS-free operation with kW level peak power. The output energy is up to 1.3 mJ, and the average power is up to 23 W at an 18 kHz repetition rate with 600 ns pulses (peak power > 2.1 kW). The PER is ≈16 dB and the M2 of the beam is 1.33 × 1.18. The coherent LIDAR Figure Of Merit (FOM) is 174 mJ*sqrt(Hz), which to our knowledge is the highest reported for a fiber laser. We also report 0.75 mJ energy and >3.7 kW peak power with down to 200 ns pulses and up to 1.21 mJ energy with a 3–5 kHz repetition rate operation of the current system.
