High Power Pulsed Laser

Using high power lasers to produce high pressure repeatable shocks in condensed materials provides an attractive tool to study shock induced processes 1 4.

High power pulsed laser.

1550 nm high power pulsed laser diode module for osa otdr applications. In other cases the application requires the production of. 2 advalue photonics has demonstrated such a pulsed transmitter option for a nasa space application that reaches pulse energy values as high as 1 8 mj at 2 5 khz. 1550 nm pulsed lasers are also offered.

Pulsed operation of lasers refers to any laser not classified as continuous wave so that the optical power appears in pulses of some duration at some repetition rate. This encompasses a wide range of technologies addressing a number of different motivations. The laser diode is optically coupled to an smf fiber pigtail and includes a. The range of average powers is from 100 w to 5 kw the pulse energy is up to 100 mj and the beam spot size is optimized for high throughput.

The engineers at par s laser center of excellence coe have over three decades of experience developing advanced pulsed co2 lasers and laser technology with specialized skills in the areas of high power and high pressure pulsed co2 laser systems laser modelling and design high voltage switching networks optics and related applications. Higher power pulsed fiber lasers with higher m 2 value are optimized for large surface area treatment applications. Additionally single and stacked devices provide up to 100watts at 850 nm laser and 905 nm laser wavelengths. Lasers are broadly classified into cw continuous wave lasers that emit a continuous light beam at constant power and pulsed lasers that repeatedly emit light pulses at short time intervals.

In the present work we report the results of numerical simulations of a single laser pulse depositing energy into a thin layer of absorbing material confined between a rigid wall and a. The scw 1532 500r laser diode module is a high power 1550 nm al rwg f p laser diode packaged in a 14 pin butterfly package. While it is extremely challenging to build a high energy all fiber alignment free pulsed laser at 1572 nm far from the er ion emission peaks around 1535 and 1545 nm see fig. Some lasers are pulsed simply because they cannot be run in continuous mode.

With more than 10 different wavelengths to choose from and repetition rates from single shot to 40 mhz pulse trains with internal or external trigger you get an extremely flexible system to fit any application. Excelitas offers a broad range of suited pulsed 905 nm lasers offering up to 100w of peak optical output power which can be increased to up to 300w of peak optical output power by physical stacking. Critical parameters of these semiconductor pulsed lasers are pulse width and rise fall times. The data sheet for this osi laser 100w laser references key features of high efficiency and high reliability as well as stable output from 40 degrees c to 85 degrees c.
