Abstract
Subject headings
Close
- A two-stage optical parametric amplifier generating 5 ns 208 kW peak power pulses in the spectral region at 1.535 mum in a diffraction-limited beam was realized in a single periodically poled KTP crystal. The maximum small-signal gain for the two stages reached 75dB and the total conversion efficiency was 30%. An analysis of the small-signal gain dependence on the M-2 of the pump beam is presented for the collinear and noncollinear OPA. Efficient spectral broadening of the signal was demonstrated in short pieces of single-mode telecommunication fiber.
