Fabrication of scale gratings for surface encoders by using laser interference lithography with 405 nm laser diodes
However, the gas laser system is expensive and its size is large, resulting in costly and bulky system; for example, the price of a commercial HeCd laser with Lc of 300 mm and an output power of 180 mW costs more than …

Cost-effective laser interference lithography using a 405 nm AlInGaN semiconductor laser
This method is cost-effective because the AlInGaN semiconductor laser has a long coherence length (∼20 m) and low price (e.g. only 1/3 that of the HeCd laser ).

Helium-Cadmium Lasers In Commercial Systems
Using published prices for approxi- mately equivalent power systems and replacement tubes the cost per milliwatt hour of 442nm radiation from a hecd laser is about 50ó of the cost of 488nm radiation from an argon ion laser.

Lasers: a 40-year perspective
There were many laser types (CO , HeNe, argon ion, dye, excimer, neodymium YAG, diode, and HeCd ) and there were many laser applications (laboratory re- search, analytical chemistry, interferometry, construction align- ment, metal working, medical, etc.). Initially, these devices sold for over $100, but prices rapidly came down to $10 to $20 due …
