Abstract
The characteristic properties of noncritically phase‐matched second‐harmonic generation in lithium triborate (LiB3O5, LBO) are investigated. Using a LBO crystal grown in our laboratory, we demonstrate that temperature‐tuned noncrictical phase‐matched second‐harmonic generation from 1.025 to 1.253 μm is achieved in a temperature range from 190 to −3 °C. The noncritical phase‐matching temperature for 1.064 μm radiation is found to be 148.0±0.5 °C with a temperature acceptance bandwidth of 3.9 °C cm.Keywords
