Tunable Lasers for DIAL Applications.

Tunable semiconductor lasers for telecommunications applications

Introduction Tunable lasers are becoming important elements in optical networks to reduce costs. They could be used particularly for systems monitoring : a reference signal is transmitted and detected on each wavelength, thus informing on transmission quality. Or inventory costs could be drastically reduced by using tunable lasers as sparing sources or even as standard sources, to avoid the obl...

3 Tunable Dye Lasers

Tunable Diode Lasers

At the recent Photonics West and Optical Fiber Conferences, companies presented many new products, ranging from mechanical products to instruments to complex laser systems. As a product engineer, there is nothing quite like the feeling of standing in the booth, talking to potential customers about the product You’ve designed or built. But the real success happens when customers buy the product ...

Nano-Electromechanical Optoelectronic Tunable Lasers

High-power widely tunable thulium fiber lasers.

Applications requiring long-range atmospheric propagation are driving the development of high-power thulium fiber lasers. We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillat...
