Abstract
Retraces of phase-matching (PM) angles and noncritical phase-matching temperatures for both type I and type II second harmonic generation in LiB3O5(LBO) are first demonstrated. By fitting to the measured PM angles at room temperature, new Sellmeier’s equations of LBO are obtained. Further analyzing the spectral and angle acceptances, we point out that LBO is particularly useful in doubling radiations near 1.3 μm such as 1.32 μm of Nd:YAG, 1.31 μm of Nd:YLF, and 1.34 μm of Nd:YAP.Keywords
