چکیده
In this paper, we report a diode side-pumped injection-seeded single-frequency Tm,Ho:YLF laser, which operated at lasing threshold and emitted 2051.2 nm. The assistance of Fabry–Pérot (FP) etalons to seed injection via mode selection was investigated. An acousto-optic Q-switched output 6.7 mJ achieved 5 Hz. A temporal pulse duration 310 ns with spectral linewidth 2.0 MHz frequency stability 0.8 root-mean-square (rms) detected. beam profile high-quality Gaussian TEM00 M2x/y ~ 1.15/1.14. This 2 μm laser source would be good candidate for ground-based wind-detection coherent Lidar system.

Injection-seeded, single-frequency, q-switched erbium:glass laser for remote sensing.
We have built and characterized an injection-seeded, Q-switched, flash-lamp-pumped, eye-safe Er:glass laser that is suitable for coherent remote sensing. The output of the device is a 400-ns, single-frequency, transform-limited pulse of 1 mJ at 1.552 mum.
متن کاملInjection-Seeded Actively Mode-locked Erbium-Doped Fiber Ring Laser for Frequency Measurement in Telecommunication Band
In this paper the mode-locking of an erbium-doped fiber ring laser with frequency shifted feedback is described. We use the configuration with an acousto-optical modulator inserted in the laser cavity that produces 1.7 ps pulses with a 40 MHz repetition frequency. The corresponding optical frequency comb has a bandwidth of more than 10 nm, centered at 1558 nm. The laser operates with external i...
متن کاملSingle-mode Brillouin fiber laser passively stabilized at resonance frequency with self- injection locked pump laser
We demonstrate a single-mode Brillouin fiber ring laser, which is passively stabilized at pump resonance frequency by using self-injection locking of semiconductor pump laser. Resonance condition for Stokes radiation is achieved by length fitting of Brillouin laser cavity. The laser generate singlefrequency Stokes wave with linewidth less than 0.5 kHz using approximately 17-m length cavity.
متن کامل240-GHz continuously frequency-tuneable Nd:YVO₄/LBO laser with two intra-cavity locked etalons.
This work reports for the first time on study of a single-frequency Nd:YVO4 laser with intra-cavity frequency doubling, in which quasi-continuous frequency tuning over an ultra-broad range is implemented with two intra-cavity locked etalons and automatic stitching between ranges of smooth scanning of the laser's output frequency. The proposed and demonstrated method allowed to continuously tune...
متن کاملFrequency jitter and spectral width of an injection-seeded Q-switched Nd:YAG laser for a Doppler wind lidar
The design of a 50 Hz single longitudinal mode, diode-pumped and frequency-tripled Nd:YAG master oscillator power amplifier is described, and the first measurements of output parameters are presented. The laser oscillator is injection-seeded by a tuneable monolithic Nd:YAG ring laser and frequency stabilized by minimising the Q-switch build-up time. The laser system will be an integral part of ...
