We describe a compact and stable setup for detecting the optical secondharmonics, in which the incident plane rotates with respect to the sample. Thesetup is composed of rotating Fresnel-rhomb optics and a femtosecondytterbium-doped fiber-laser source operating at the repetition frequency of 10MHz. The setup including the laser source occupies an area of 1 m2 and isstable so that the intensity fluctuation of the laser harmonics can be lessthan 0.2 % for 4 h. We present the isotropic harmonic signal of a gold mirrorof 0.5 pW and demonstrate the integrity and sensitivity of the setup. We alsoshow the polarization-dependent six-fold pattern of the harmonics of afew-layer WSe2, from which we infer the degree of local-field effects. Finally,we describe the extendibility of the setup to investigate the samples invarious conditions such as cryogenic, strained, ultrafast non-equilibrium, andhigh magnetic fields.
