About Us

Lic engineering is the one of world leading providers of innovative CO2, Capacitor Charging & High Power Laser Diode Driver/Power supplies.

Our specialties are for the most compact/high power water-cooled switch-mode power supplies and high speed , high current, high voltage & high power nano-pulse technologies.

Super Pulse and Ballastless technologies are the original development by Lic engineering in the early 1980s for the CO2 surgical laser systems. Super Pulse is accomplished by combination of secondary H.V multiplier, the primary high peak current/high frequency switching circuit and negative impedance of a CO2 laser tube. The compressed stored secondary energy in the multiplier is rapidly released by breakdown of negative impedance of the laser tube and thus the narrow high peak laser power is outputted.  The Ballastless operation is performed by using drooping characteristic of the secondary multiplier that is carefully designed to achieve Super Pulse and Ballastless operation at the same time. The high frequency Ballastless power supplies designed by our engineer replaced all the bulky H.V X-former, expensive vacuum tube, and H.V ballast resisters used for the traditional power supplies in that age.

Since the first product was developed in early 1980s, our CO2 laser power supply has used "series resonant topology", which make a switching current "sinusoidal" to reduce the switching loss and to push a high current into the secondary circuit in very short time. This enabled our products to achieve the high peak current of Super Pulse, that is capable of 10 times higher peak power than CW power and very compact in size.

In 1986, Inoue founded Lic engineering (formerly Laser Innovations Corp.,) in Sunnyvale, CA to manufacture and market this new technology. In the early 1990s, Lic engineering introduced its first flat-type water cooled CO2 laser power supply, the CSF-series. In the mid-'90s, the company introduced cost efective 600W/1KW CPF-series and the highest power of 25KW CSF-25000PD & CSF-25000/8.  These CSF-& CPF series are the most popular and long run products among our products line. Since the company introduced the first water cooled power supply in the late-'80, it continued to manufacture the unique water cooled CO2, Yag, Capacitor charging laser power supply.

In 2005, the company introduced the first high peak current, fast rise time and ultra high power laser diode drivers, high power QCW laser diode driver, LD-1500/3000, LSP-500, that are capable of Super Pulse and LSP (Lic Super Pulse).  LD & LSP series are now wide variety of product line:

LSP-XXXX-series high voltage, high power, high speed laser diode drivers can achieve 5KA/15KV/20ns pulse width with the rise time of 5-12ns.

LD-XXXX/QCW-series high speed, high current, high QCW laser diode drivers have the output power to 1KA/1KV/1MW of QCW power.

LS-XXXX-series high frequency, high pulsed current laser diode driver/gas discharge power supply can achieve the pulse rate up to 5MHz with pulse width of 5ns-100ns.

Through over 28 years of investment in research and development, Lic engineering has become an innovator both in product design and manufacturing processes as well. The result is the world's most compact, water cooled H.V power supply, and high power, high speed, high current laser diode driver/pulse generator.
