We present two distinct ultra-low frequency noise lasers at 729 nm with a fast of 30 Hz 2 /Hz, corresponding to Lorentzian linewidth 0.1 kHz. The characteristics both lasers, which are based on different types laser diodes, investigated using experimental and theoretical analysis focus identifying the advantages disadvantages each type system. Specifically, we study differences similarities in mode behavior while tuning reduction. Furthermore, demonstrate locking capability these systems...

Narrow-linewidth continuous wave lasers are indispensable tools in experiments based on ultra-cold atoms like optical clocks or quantum computers [1]. Cooling and pumping of the is typically done with commercially available external-cavity diode (ECDL) linewidths order 100 kHz. Driving so-called clock transition requires frequency noise (FN) which orders magnitude smaller than those systems.
Compact and robust external-cavity diode laser (ECDL) systems are a mandatory requirement for many next-generation quantum technology applications, e.g. communication sensors. Today's commercially available ECDLs used proof-of-principle demonstrations of such however do not meet the requirements use in real-world environments. We investigate novel design compact ECDL suitable integration into first applications. Experimental results prototypes presented compared to numerical simulations.
