We improve the output of a MOPA system that emits single-frequency high-energy optical pulses using a large mode area Er-doped fiber amplifier pumped by a cascaded Raman fiber laser with a low 150 Hz repetition frequency. It is found that the unwante

The realization of cold atoms using a compact and low-power-consumption experimental setup is indispensable for cold atom experiments, including optical clocks and quantum simulations. We demonstrate the direct loading of Yb atoms into a 3D magneto-o

Waveguide-based devices are essential for highly efficient nonlinear optical conversion. However, the nonlinearity associated with the conversion in such devices is not self-evident. The authors present a method using optical frequency metrology to r

We generate a broadband frequency comb using a WG-PPLN and measure the offset frequency of the comb by using a frequency-stabilized laser at 532 nm. The visible comb is generated through χ(2) process.

We have developed iodine-stabilized lasers using ultra-compact diode laser modules at 531, 561 and 594 nm. The achieved frequency stabilities were typically 4×10−13 at an averaging time of 1000 s.

We demonstrate high-resolution spectroscopy of molecular iodine using coin-sized laser modules at 531 nm, 561 nm, and 594 nm. Hyperfine components of the R(36)32-0, P(64)20-0, and P(69)12-1 transitions are observed with a signal-to-noise ratio of sev
