Configurable multiwavelength narrow linewidth laser system for quantum applications

Presented in: SPIE Quantum West 2023 Authors: Kostiantyn Nechay, Luukas Kuusela, Ossi Mäkinen, Riina Ulkuniemi, Pekko Sipilä, Kalle Palomäki, Petteri Uusimaa    Presented in: SPIE Quantum West 2023 Authors: Kostiantyn Nechay, Luukas Kuusela, Ossi Mäkinen, Riina Ulkuniemi, Pekko Sipilä, Kalle Palomäki, Petteri Uusimaa   Single-frequency laser sources serve as a backbone for quantum computing and metrology technologies and applications. Availability of integrated laser systems delivering tailored multiwavelength emission across optical spectrum is a defining factor for further quantum technologies development and commercialization. Modulight demonstrates highly integrated ML6600 laser system for cooling and repumping of 87Rb atoms at D2 line. Such laser system incorporates driving electronics, internal spectroscopy-locked Continue reading →

High aspect ratio DBR gratings for narrow linewidth red lasers

Presented in: SPIE Quantum West 2023 Authors: Luukas Kuusela, Riina Ulkuniemi, Timo Aho, Petteri Uusimaa    Presented in: SPIE Quantum West 2023 Authors: Luukas Kuusela, Riina Ulkuniemi, Timo Aho, Petteri Uusimaa   In interferometry, spectroscopy, and holography, HeNe lasers or semiconductor lasers with external wavelength stabilization have been widely used to achieve the required narrow linewidth at 633 nm. Semiconductor lasers utilizing wavelength selective grating fabricated on semiconductor chip enable the miniaturization of laser systems while also providing numerous advantages such as low energy consumption, reliability and tunability by temperature and injection current. Moreover, DBR gratings reduce the complexity of the laser system compared Continue reading →
