Description: LPI-102 ЛПИ-102 VINTAGE RARE SOVIET SEMICONDUCTOR INFRARED LASER NEW NOS Semiconductor injection multimode pulsed laser. Wavelength 875+75 nm.Producer - "VOSKHOD", Kaluga It is used as a source of laser radiation in the infrared range in devices for special and civil purposes, laser medical equipment. Made using a gallium arsenide emitting laser diode, has a built-in hybrid microassembly of the pump current generator. Electrical parametersAverage power of laser radiation pulse - not less than 2.5 W (2.7...6.5 W)*Duration of laser radiation pulses (by level 0.5) - not less than 70 ns (60 ns)*Laser pulse repetition frequency - 6.0±0.6 kHzCurrent consumption - no more than 50 mA (40 mA) *Supply voltage - 20±0.1 VOperating temperature range -60...+60 'CMinimum operating time - 20 h (30 h)** data for civil devices Semiconductor laser emitter LPI-101 is the first domestic semiconductor infrared laser developed by FSUE "NII "Polyus"at the very end of the 80s. This emitter is still being mass-produced by OJSC Voskhod-KRLZ, and the former name of this enterprise"Kaluga Radiotube Plant". Initially, the LPI-101 laser was created for use in military equipment. But quickly enoughThe infrared laser head has been used in medicine and in some industries, such as engraving.For the first time, such an emitter fell into the hands of the author back in 1991, and the jokers then called him the "eye of the KGB".Yes, try to type the name "LPI" on the English keyboard layout yourself, and you will understand this subtle humor of the laser developers. Here it is, the same head, released back in 1991. This emitter is currently in the author's collection, it is new,and is fully operational, giving out the required radiation power when connected: The case of such a laser emitter is sealed. Inside the case there is a simple generator of pump current pulses in an integrated version.This working integrated circuit contains a gallium arsenide laser emitting pulsed multimode IR diode.A charging resistor, two storage capacitors and two switching dinistors are connected in parallel to it. Both dinistors are connected in series,and selected under production conditions according to parameters that must be completely identical. Discharged through these dinistors are storageThe emitter capacitors form the pump current pulse. A charging resistor connected in parallel with the laser diode is necessary to charge the storagecapacitors and the operation of the laser emitter as a whole, but it also reduces the efficiency of the entire system. Each semiconductor laser emitter LPI-101 has an individual serial number stamped on its base: In 1980, the plant began small-scale production of LPI-101 and LPI-102 lasers, and since the mid-80s, the plant has mastered the mass production of Uzor and Urozhay medical laser devices.In 1987, the Uzor laser device, manufactured by the plant, was awarded the Gold Medal of VDNKh. *Shipping: We ship worldwide by Registered and priority Lithuania Post Delivery service.Tracking number will be provided.
