Thermal lens forming element |
摘要 |
A thermal lens forming element includes a first chamber serving as a control light absorbing region, which is configured as a columnar body or an N prismatic body (wherein N is an integer equal to or greater than 4) circumscribing the columnar body and filled with a control light absorbing dyestuff solution containing a solvent having a viscosity of 0 to 3 mPa·s at 160° C. or above and a ratio of the viscosity of the solvent at 160° C. to a viscosity of the solvent at 40° C. not less than 1 and not greater than 6, wherein the columnar body or the N prismatic body circumscribing the columnar body has a central axis coinciding with an optical axis of incident signal light. The first chamber is connected to a second chamber via a solution channel and a dam. The dyestuff solution and a bubble of an inert gas are confined in the second chamber.
