a Schematic of the experimental setup; b Transmission spectrum of Nd: YAG microcavity in the laser emission band, with FSR (free spectral range) of 6.62 nm. Simulated Cross section of absolute of the electric field distribution c and the transmission spectrum d of TE147,01, with Q factor of 1.08 × 104. e Transmission spectrum of the Nd: YAG microcavity in the telecom wavelengths, with FSR (free spectral range) of 14.3 nm. Simulated Cross-section of absolute of the electric field distribution f and the transmission spectrum g of TE96,01, with Q factor of 2.8 × 105
