795&894nm Single-Frequency VCSEL V00140
Single-frequency VCSELs (vertical-cavity surface-emitting lasers) from US-based Vixar offer narrow linewidth and low emission divergence, with precise tuning to the Rb D1 absorption line (795 nm) or Cs D1 absorption line (894.6 nm). The laser chip supports high-temperature operation at 60℃-110℃, matching atomic absorption cell operating temperatures to ensure high reliability of packaged devices. These Vixar single-frequency VCSELs are ideal light sources for atomic magnetometers and chip-scale atomic clocks (CPT atomic clocks).
