Title (EN) LIGHT SOURCE DEVICE AND LASER LIGHT IRRADIATION DEVICE
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE ET DISPOSITIF DE RAYONNEMENT DE LUMIÈRE LASER
(JA) 光源装置及びレーザ光照射装置
Abstract:
(EN) This light source device is provided with: a fiber laser that emits randomly polarized laser light; a polarization beam splitter that splits the laser light emitted by the fiber laser into first split laser light and second split laser light for each polarization component; a wavelength plate that changes the polarization direction of the second split laser beam so as to be the same as the polarization direction of the first split laser beam; and a half mirror that combines the first split laser beam which was split by the polarization beam splitter and the second split laser beam for which the polarization direction was changed by the wavelength plate, and outputs the result as combined laser light.
(FR) L'invention concerne un dispositif de source de lumière comprenant : un laser à fibre qui émet une lumière laser polarisée de manière aléatoire; un diviseur de faisceau de polarisation qui divise la lumière laser émise par le laser à fibre en une première lumière laser divisée et une seconde lumière laser divisée pour chaque composante de polarisation; une plaque de longueur d'onde qui change la direction de polarisation du second faisceau laser divisé de façon à être la même que la direction de polarisation du premier faisceau laser divisé; et un demi-miroir qui combine le premier faisceau laser divisé qui a été divisé par le diviseur de faisceau de polarisation et le second faisceau laser divisé pour lequel la direction de polarisation a été changée par la plaque de longueur d'onde, et délivre le résultat sous la forme d'une lumière laser combinée.
(JA) 光源装置は、ランダム偏光のレーザ光を出射するファイバレーザと、ファイバレーザで出射したレーザ光を、偏光成分ごとに第1分岐レーザ光と第2分岐レーザ光とへ分岐する偏光ビームスプリッタと、第2分岐レーザ光の偏光方向を第1分岐レーザ光の偏光方向と同じになるように変える波長板と、偏光ビームスプリッタで分岐された第1分岐レーザ光と波長板で偏光方向を変えた第2分岐レーザ光とを、合波して合波レーザ光として出力するハーフミラーと、を備える。
