    We developed an efficient, high-power red laser using a single periodically poled lithium niobate crystal. This novel frequency conversion method achieves 2.5W of 629-nm output from a diode-pumped laser.

    Area of Science:

    • Optics and Photonics
    • Laser Physics
    • Nonlinear Optics

    Background:

    • High-power, continuous-wave (cw) visible lasers are crucial for various applications.
    • Existing methods for generating red laser light often involve complex setups or lower efficiencies.
    • Periodically poled lithium niobate (PPLN) offers versatile nonlinear optical functionalities.

    Purpose of the Study:

    • To report an efficient, high-power, cw 629-nm laser source.
    • To demonstrate a novel frequency conversion scheme integrating two nonlinear processes in a single PPLN crystal.
    • To achieve high conversion efficiency and output power for visible laser generation.

    Main Methods:

    • Utilized a diode-pumped neodymium-doped yttrium aluminum garnet (Nd:YAG) laser as the pump source.

    • Obtained a high output power of 2.5W at 629 nm with 11.8W of input pump power.

    Conclusions:

    • The integrated two-step frequency conversion in a single PPLN crystal is an effective method for generating high-power visible lasers.
    • This approach offers a compact and efficient solution for producing 629-nm laser light.
    • The demonstrated technology has potential applications in areas requiring high-power red laser sources.
