The resulting laser signal, featuring the defined pulse shape, is then output to a single mode fibre. In order to program the pulse shape, the PPL 512 \/ PPA 512 is connected to a host computer via a standard USB interface. The very compact form factor makes it ideal for integration into larger amplified laser chains. By programming fast current slopes, not only nanosecond pulses can be generated but also gain switched operation becomes possible, which results in picosecond optical output pulses. Also, undesired ringing effects at fast switch-on transients can be reduced by defining specific current ramps. Moreover, saturation effects of optical amplifiers can be pre-compensated, which makes the device an ideal seeding source for fibre or solid-state amplifiers.<\/p>\n<p><strong>Programming arbitrary pulses profiles \u2013 byte by byte<\/strong><br \/>\nThe PPL 512 \/ PPA 512 is based on a programmable waveform platform capable of generating pulse patterns in a cyclic sequence of 512 bytes. The 512 bytes are stored in a special high-speed memory that can be read out at the full speed of 5 GS\/s. This results in a timing resolution of 200 ps per byte (other values may be made available on request). With such a 512 byte data set, arbitrary pulse shapes can be defined with an amplitude resolution of 8 bits (0 to 255). This pre-defined sequence can then be run as a gapless loop at the full speed of 5 GS\/s or started and stopped by an external control signal.<\/p>\n<p><strong>One laser platform, multiple variations<\/strong><br \/>\nMultiple model versions can be derived from the main PPL 512 \/ PPA 512 laser platform, depending on the internal architecture and mode of modulation. The available palette encompasses:<\/p>\n<ul>\n<li>The direct modulation of the laser diode (PPL 512 \u2013 xxxx <sup>[1] <\/sup>)<\/li>\n<li>The modulation of the CW driven laser diode via a semiconductor optical amplifier (PPL 512 \u2013 xxxx SOA <sup>[1] <\/sup>)<\/li>\n<li>The modulation via a semiconductor optical amplifier NOT including the CW diode (PPA 512 \u2013 xxxx <sup>[1] <\/sup>)<\/li>\n<\/ul>\n<p>The PPL 512 \/ PPA 512 can be configured to provide programmable pulses at wavelengths such as 1030 or 1064 nm, 1.5 or 2 \u00b5m, as well as many wavelengths in the visible range.<\/p>\n<p><small><sup>[1]<\/sup> The \u201cxxxx\u201d label indicates the laser\u2019s emission wavelength<\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Programmable Pulsed Laser Programmable nanosecond pulse shapes 0.1 ns to CW Average power up to 20 mW Extinction ratio up to 70 [&hellip;]<\/p>\n","protected":false},"featured_media":49341,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[109],"product_tag":[],"class_list":{"0":"post-49267","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-short-pulse-ns-ps-fs-lasers","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) -
