摘要： A wavelength conversion element manufacturing method capable of realizing, in a wavelength conversion element having a structure in which a thin film substrate having a periodic polarization inversion structure and a support substrate are laminated, highly efficient wavelength conversion by confining light in a cross-sectional area smaller than in the known art. The manufacturing method includes steps of forming a periodic polarization inversion structure on a first substrate made of a second-order nonlinear optical crystal and forming a damage layer in the first substrate by implanting ions from one substrate surface to obtain a first substrate for bonding, directly bonding a second substrate having a bonding surface having a smaller refractive index than the first substrate to the one substrate surface of the first substrate at the bonding surface, and peeling the first substrate directly bonded to the second substrate being the support substrate with the damage layer as a boundary to remove a part of the first substrate.

摘要： The disclosed laser system is configured with a laser source outputting light at a fundamental frequency. The output light is incident on a frequency converter operative to convert the fundamental frequency to a higher harmonic including at least one frequency converting stage. The frequency converter is based on a SrB4O7 (SBO) or PbB4O7 (PBO) nonlinear crystal configured with a plurality of domains. The domains have periodically alternating polarity of the crystal axis enabling a QPM use and formed with each with highly parallel walls which deviate from one another less than 1 micron over a 10 mm distance.

摘要： A method, system and apparatus for automatically determining operating conditions of a periodically poled lithium niobate crystal in a laser system are provided. The system comprise: a laser; a periodic poled lithium niobate (PPLN) crystal for receiving laser input from the laser; a temperature control device for adjusting the temperature of the PPLN crystal; a temperature sensor for monitoring the temperature of the PPLN crystal; and a computing device. While the PPLN crystal is receiving laser input, temperature of the PPLN crystal is changed using the temperature control device. The computing device monitors the temperature of the PPLN crystal and corresponding power of the temperature control device during the changing, the temperature monitored using the temperature sensor. The computing device determines one or more of operating conditions of the temperature control device and an operating temperature of the PPLN crystal from a function of the power vs. the temperature.
