We theoretical ly investigate several thermally induced limitations in the semi monolithic optical parametric oscillator (OPO) that prepare the squeezed vacuum on alkali metal atomic transition s D ue to the severe pump beam absorption, the inevitable temperature fluctuations cause the squeezed quadrature angle rotation and even a slight change can decrease the squeezing level significantly , especially at the low er measurement frequencies ; in the the thermal lensing is shown to be also important constraint and must be taken into account. In order to reduce the deleterious effects of thermal effect, one should utilize OPO eigenmode waist radius of more than 45 μm in practice.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
