“…As the environmental temperature increases, the thermal expansion effect and thermal-optical effect will respectively cause an enlargement in the microsphere's dimensions and refractive index, leading to a redshift in its resonant wavelength. The shift of the wavelength Δλ as the function of temperature can be expressed as [22],…”

We present a low-loss Er 3+ -doped silicate microsphere laser, exploring its temperature sensing characteristics. We measure the threshold power of the Er 3+ -doped silicate glass microsphere laser under 980 nm pumping, achieving an impressively low value of 3.14 mW. Subsequently, in order to study the effect of temperature on the laser, the microsphere laser is placed into a temperature controller, and high-temperature sensitivity of 17.56 pm/℃ is obtained in the experiment. The proposed microsphere is significant for applications in lasing and temperature sensing, offering substantial advantages in terms of lower threshold power and heightened temperature sensitivity.
