Laguerre-Gaussian (LG) modes possess an orbital angular momentum and a ring-shaped spatial form, and they have been attracting much interest in various applications, including optical manipulation, optical/quantum communication, and super-resolution microscopes. Further extension of applications desires strongly the high quality LG mode laser sources with wavelength versatility. Self-Raman lasers enable us to realize ultra-compact laser systems with versatile wavelengths and excellent beam quality.
