Title: Understanding fifth-harmonic generation in CLBO

Abstract

Here, we report on results of fifth harmonic generation in Cesium Lithium Borate (CLBO) using a three-crystal cascaded frequency conversion scheme designed to study the energy balance of the final sum frequency generation stage. The experimental setup independently combines the first and fourth harmonic of a Nd:Glass laser in a 5mm thick CLBO crystal. Energy balance between the incoming and output energy is close to unity when the CLBO is out of phase matching and approximately 80% when the crystal is in phase matching. A detailed analysis of the residual fundamental and fourth harmonic energy indicates 5th harmonic light is being generated but only 26% is unaccounted for. We attribute the missing light to linear transmission loss in the CLBO oven. The ratio of the output to input energy is unity when the missing 5th harmonic is incorporated into the calculations. Two-dimensional plane wave mixing simulations show agreement with the results at lower intensities.

Figure 1 Figure 1: Diagram of the experimental setup for the fifth harmonic generation experiment. A waveplate (WP1) is used to adjust the energy balance between the 1ω and 4ω sections. A second waveplate (WP2) offers independent control of 1ω energy without affecting 4ω energy. A type I 18mm KDP doubler (SHG)more » was used to generate the second harmonic. Fourth harmonic was generated using a 6mm type I KDP (4HG) crystal. The residual colors from the fourth harmonic generation process are removed using an array of 4ω high reflectors. Input energy is measured in both sections before the generated 4ω is mixed with the 1ω in a type I 5mm CLBO crystal to make fifth harmonic.« less
