The Bit Rate Multiplier (BRM) increases the repetition rate of a pulsed ps laser by 2, 4, 8, and 16 times using Mach-Zehnder interferometers with variable time delay in one arm. In conjunction with Calmar’s Eureka fiber based picosecond lasers, pulse streams up to 640 GHz and beyond can be generated.

Eureka – High Repetition Rate Fiber Based Picosecond Laser (PSL)

Eureka Picosecond Laser

The fiber-based picosecond laser (PSL) is an actively mode-locked fiber laser with repetition rates available from 5 to 40 GHz.

This picosecond laser provides a stable and reliable optical clock with turnkey operation. Along with a portable design, the Eureka series are portable lasers, with user-friendly front panel control knobs for flexible adjustment of wavelength and output power. The wavelength can be tuned throughout the C-band. The timing jitter is as low as 50 fs and the side mode suppression is better than -75 dB. An output power of greater than 20 mW obviates the need of an additional optical amplification stage.

The PSL-10-TT C-band 5 ~ 20 GHz picosecond fiber laser offers continuously tunable repetition rate from 5 to 20 GHz that provides a stable and reliable optical clock with turnkey operation. The pulse width can be tuned from 1.5 to 10 ps, with transform-limited spectral width and a better than -20 dB pedestal.

The PSL-40-TT C-band 40 GHz picosecond fiber laser is an actively mode-locked fiber laser with a repetition rate from 38 to 42 GHz that provides a stable and reliable optical clock with turnkey operation. The pulse width can be tuned from 0.8 to 5 ps, with transform-limited spectral width and a better than -20 dB pedestal.

The Eureka series of lasers are rugged, stable and an industry standard, with millions of hours of field use.

1530 ~ 1565 nm

Product Tunable Rep Rate Pulse width Avg. Power Option
PSL-10-TT 5-20 GHz 1.5 ~ 10 ps >20 mW Tunable Pulse Width
PSL-40-TT 38-42 GHz 0.8 ~ 5ps >20 mW Tunable Pulse Width

For increasing repetition rate, we suggest use of our Bit Rate Multiplier (BRM)

For increasing output power, use our laser amplifier – Coronado

"Calmar's products have continued to perform well, even after several years, and are much lower maintenance than our other mode-locked lasers"
