Semiconductor Laser, Ipc

This laser emits an intense monochromatic red beam of wavelength 630 nm at 0.9 mW (Class II operation). Typical beam divergence is approximately 1 millirad. The laser is ideal for the demonstration of the behaviour of light in a visually effective way, reinforcing the practical work carried out by pupils using white light. It is an essential tool to develop basic understanding of the passage of light through different media, slits etc. The laser beam can be modulated by applying an external digital or analogue waveform to the 3.5 mm jack socket on the rear panel. Alternatively, the beam can be modulated by the internal generator which produces 0.1 µs pulses at approximately 1 MHz. This allows speed of light experiments to be easily performed. The passage of light through light guides and optical fibres can be demonstrated by filling a glass or plastic tube or U-tube with very dilute milk.
The growth of laser-based communication systems and research into the use of lasers in computers of the future make this an essential piece of equipment to bring up-to-date relevance into teaching.
The laser is powered by a 6LR61 (PP3) battery or external smoothed and regulated supply, has adjustable focus, no warm-up time and has a key operated safety switch. Housed in a robust anodised aluminium case. Supplied with key.
