The contribution is oriented towards frequency stabilization of frequency-doubled Nd:YAG lasers for nanometrology through spectroscopy in molecular iodine. We designed and manufactured a series of new type of iodine absorption cells and tested the frequency stability of the laser stabilized with these cells. The set of starved iodine cells does not need a cold finger for stabilization of the pressure of the absorbing media due to the saturation pressure of iodine is defined during the iodine filling process. A second part of the contribution is focused to absorption cells made of borosilicate glass instead of traditionally used fused silica. Absorption cells prepared by these two approaches were used for frequency stabilization of Nd:YAG laser by the linear and saturation spectroscopy in different environmental conditions and resulted frequency stability was compared to commonly used laser standard based on quartz silica glass cell. The achievable hyperfine transitions linewidths were studied in detail.
