Fast online rubidium DPAL atomic concentration measurement by 420 nm probe laser.

The alkali atom concentration plays an important role in the performance of a diode pumped alkali vapor laser (DPAL). At the rubidium DPAL operational region, the alkali concentration is as high as 10-10, which is "optically thick," or opaque, for the 780 nm or 795 nm doublet D lines when the traditional scanning absorption spectrum method is used for concentration measurement. To solve this problem, we propose the use of a probe laser of 420 nm, which corresponds to the 5 to 6 transition and has a lower absorption cross section compared to the D-line doublet.

Fast on-line rubidium DPAL atomic concentration measurement by 420 nm probe laser: erratum.

We present an erratum to our recent work [Appl. Opt.60, 10862 (2021)APOPAI0003-693510.

[Dynamics of Proliferation and Differentiation after Transplantation of Hematopoietic Cells in Mouse].

Objective: To observe the dynamic changes of hematopoietic reconstitution and multiple lineages differentiation at early phase after transplantation.

Methods: Whole bone marrow mononuclear cells (wBMMNC, 5×10) and enriched c-Kit hematopoietic stem/progenitor cells (HSPC, 3×10) from the BM of B6-Ly5.1 mice were transplanted into lethally irradiated B6-Ly5.
