发明名称 WAVELENGTH CONVERTING DEVICE, LASER, AND METHOD TO STABILIZE THE WAVELENGTH CONVERSION EFFICIENCY
摘要 Proposed is a wavelength converting device (100) comprising a non-linear optical crystal (10) having periodically poled regions (20,30) with alternating polarity. The device (100) is characterized in that the period (41,42) of the poled regions along an axis (X) of the device vary in a direction (Y) perpendicular to the axis. The invention is based on the insight that a poling period corresponds to a given temperature. Thus, providing different poling periods along a direction in the wavelength converting device advantageously allows correlating the position of the device along that direction with a temperature.
