VECSEL gain characterization.
We present the first full gain characterization of two vertical external cavity surface emitting laser (VECSEL) gain chips with similar designs operating in the 960-nm wavelength regime. We optically pump the structures with continuous-wave (cw) 808-nm radiation and measure the nonlinear reflectivity for 130-fs and 1.4-ps probe pulses as function of probe pulse fluence, pump power, and heat sin...
متن کاملSpectral and noise characterization of a 852 nm dual-frequency VECSEL
Coherent population trapping (CPT) is a common technique used in compact atomic clocks which requires two-phase coherent laser modes with a frequency difference in the GHz range for alkali atoms [1]. To improve the performance vs size trade-off of Cs atomic clocks, we develop a laser source generating two crosspolarized coherent laser fields at 852 nm. It relies on the dual-frequency and dual-p...
متن کاملOptically pumped VECSELs: review of technology and progress
Vertical-external-cavity surface-emitting lasers (VECSELs) are the most versatile laser sources, combining unique features such as wide spectral coverage, ultrashort pulse operation, low noise properties, high output power, high brightness and compact form-factor. This paper reviews the recent technological developments of VECSELs in connection with the new milestones that continue to pave the ...
متن کاملMeasurement of the coupling constant in a two-frequency VECSEL.
We measure the coupling constant between the two perpendicularly polarized eigenstates of a two-frequency Vertical External Cavity Surface Emitting Laser (VECSEL). This measurement is performed for different values of the transverse spatial separation between the two perpendicularly polarized modes. The consequences of these measurements on the two-frequency operation of such class-A semiconduc...
