We report on an efficient blue light generation in periodically poled LiTaO3 by the frequency tripling of a quasi-continuous 1342 nm Nd:YVO4 laser. The period of the sample was 14.778 μm. Blue light with an average power of 138 mW was generated from a 18 mm long crystal in a single-pass process under an average fundamental power of 713 mW. The internal conversion efficiency was 19.3%.

This paper investigates the problem of computing all maximal contractions of a given formula set F with re- spect to a consistent set A of atomic formulas and negations of atomic formulas. We first give a constructive definition of minimal inconsistent subsets and propose an algorithmic framework for computing all minimal inconsistent subsets of any given formula set. Then we present an algorithm to com- pute all maximal contractions from minimal inconsistent sub- sets. Based on the algorithmic framework and the algorithm, we propose a general framework for computing all maximal contractions. The computability of the minimal inconsistent subset and maximal contraction problems are discussed. Fi- nally, we demonstrate the ability of this framework by apply- ing it to the first-order language without variables and design an algorithm for the computation of all maximal contractions.
