Lee laser Series 800 Nd: Yag Laser 825 TQ/CE Innovative Laser Solution

The series 800 represents a new generation of CW and Q switched Nd: YAG lasers from Lee Laser.

It incorporates significant optical head design improvements combined with a power supply that is engineered to meet future uniform international electrical codes. The power supply also uses a new concept of arc lamp power control.

Although the fundamental design of the Series 800 Lasers is similar to that of the highly successful Series 700, performance comparisons reveal the following about the Series 800.

More Efficient - Comparable laser power at reduced arc lamp power.

Greater Q-Switched Peak Pulse Power - Shorter pulse width at comparable pulse rates and average power.

Longer Arc Lamp Lifetime

Better Q-Switched Peak Pulse - Most noticeable for models at elevated pulse rates above 10khz.

This machine is part of our unique Solar Panel Wafer & Semiconductor Machinery event.

This event is a complete working cell of equipment used in the manufacture of the BP Solar Saturn Cell (Laser Grooved Buried Contact) for solar concentrator systems by Solar Capture Technologies, UK. This successful R&D process is now being industrialised and this unique collection of machinery is surplus to requirements.

Design Features

Power Station

Power Supply 
Built according to IEC 950 design standards for operator safety
Constant power source rather than constant current source which improves arc lamp power stability and uniform arc lamp performance, compensates for lamp to lamp voltage differences.

External computer interface. Optically isolated interface circuit for external laser power control, plus output ports for computer monitor of system internal fault diagnostics.

Q-Switch Driver
Designed primarily for computer control.
Internal Frequency control - Knob on front panel adjusts range over range 2-10khz
Lower limit (2 khz) and upper limit (10khz) set for test purposes.

Optical Assembly
Changes only to head block assembly. Design improvements produce significant results:

  • Better Q-switch pulse stability at higher frequencies
  • Improved optical pump efficiency
  • Longer arc lamp lifetime
