摘要
报道了基于充气负曲率空芯光纤的红绿蓝色拉曼激光实验。利用1064 nm亚纳秒微片脉冲激光器抽运一段充高压氢气的Ice-cream型负曲率空芯光纤,通过氢气分子的级联受激拉曼散射,同时获得了波长分别为737.6,564.2,457.1 nm的一阶、二阶、三阶振动反斯托克斯激光输出。通过调节抽运激光功率和气体气压,可以控制红、绿、蓝三色激光的相对强度和输出模式。
Abstract
The experiment of red, green and blue laser generating simultaneously in gas-filled negative curvature hollow-core fiber is reported. A hydrogen-filled Ice-cream negative curvature hollow-core fiber is pumped with a high peak-power, narrow linewidth, subnanosecond pulsed 1064 nm microchip laser, generating 737.6, 564.2, 457.1 nm pulses corresponding to the first, second and third vibrational anti-Stokes waves by cascaded stimulated Raman scattering of hydrogen molecules. The relative intensities and output modes of red, green and blue laser can be controlled by adjusting the pump power and the pressure of hydrogen filled in the hollow-core fiber.
